Figure 2. Mounting Receiver/Driver Box Into LWM41 Wall Mount

3.0 INSTALLATION

LRD41 receiver/driver installation is usually just part of a larger system installation that includes the prior routing of power and other cable wiring (Coax, Alarm and Aux) to the openings where they will be used. To install a receiver/driver at any one location, perform the following steps (the step sequence is only summarized below; fleshed out instructions for each step are referred to by section number):

1. Assemble small hardware items such as glands, gasket, plates and receiver/ driver anchoring hardware that will be needed during the installation.

2. Mount the LWM41 (Legacy Wall Mount) into which the LRD41 receiver/driver will be installed. Refer to the LWM41 manual (C283M) that accompanied your unit for installation instructions.

3. After mounting the LWM41, route the appropriate cables and wiring into the LWM41 (see Section 3.1).

4. Attach input power cable leads to the bracket switch and mount the bracket switch on the LWM41 (see Section 3.2 ).

5. Connect applicable cables, (e.g., Coax) and wires (e.g., Alarm and Aux) to their provided external mating connectors (if applicable) in preparation for at- taching these connectors to their proper mating connectors on the LRD Rear Panel itself (see Section 3.4 ).

6. Install the LRD41 receiver/driver into the LWM41 (see Section 3.3 and 3.4).

TOOLS FOR INSTALLATION

These will be needed for attaching the power connections to the switch bracket terminal block. It is important for cable routing purposes that the steps be followed in their recom- mended sequential order.

Small standard-head screwdriver 5/16-inch hex wrench

NOTE: All directional references, un- less otherwise noted, assume the mount has been properly installed on a suitable mounting surface, and that the installer is looking straight at the mount from the nose back toward the mounting plate.

NOTE: In bottom-entry/gland instal- lations, install the BNC connectors to the video out/sync cables only after the cable has been threaded through the glands. The BNC connectors will not fit through the PG-13 glands.

3.1 INSTALLING CABLING TO WALL MOUNT

The LWM41 mount provides a great deal of flexibility in installations. Listed below are the most common configurations for bringing the cabling into the LWM41 mount. In each case, note that the supplied gaskets, glands and block-off plates must be used appropriately to achieve a NEMA 4 rating.

3.1.1 Rear Entry Cabling

Cabling can be brought into the LWM41 directly from a wall into the rear of the mount arm. In the absence of conduit, the provided gasket must be used to form a seal. This is especially important when mounting against a rough surface.

1. Pull the cabling into and through the mount allowing enough slack to make all connections (preferably 4 to 6 inches).

2. Proceed with the connections in Section 3.2.

3.1.2 Rear Entry with Conduit

Cabling can be brought into the LWM41 through the rear of the mount, in conduit. The provided conduit block-off plate must be used in conjunction with the gasket to form an appropriate seal.

1. Secure the cable conduit to the block-off plate.

2. Pull the cabling into and through the mount allowing enough slack to make all connections (preferably 4 to 6 inches).

3. Proceed with the connections in Section 3.2.

CHASSIS GROUND WIRE (PART OF THE LWM) IS ATTACHED TO THE LRD SWITCH BRACKET DURING ITS IN- STALLATION (REFER TO SECTION 3.2 AND FIGURE 5) APPROXIMATE LOCATION

OF WIRE

IMPORTANT: Using Figure 3, orient the input wiring so that the power cable feeds (either from the wall, or through the glands on the bottom of the mount) into the LEFT side of the mount, and the video, sync aux/alarm & RS422 cables/wires feed into the RIGHT side of the mount.

Pelco Manual C557M (10/99) 11

3.1.3 Bottom Entry Cabling

Cabling can enter the LWM41 through the bottom of the mount arm. The cable glands and gland plate must be used to form a seal.

1. Remove the cover plate from the bottom of the mount arm.

2. Thread the cabling through the glands/gland plate.

3. Feed the cable through the mount, leaving adequate slack for connections (preferably 4 to 6 inches).

4. Then tighten the glands and secure the gland plate into place on the bottom of the mount.

5. Proceed with the connections in Section 3.2.

3.1.4 Bottom Entry with Conduit

Cabling contained in conduit can enter the LWM41 through the bottom of the mount arm. The gland plate (with glands removed) must be used to form a seal.

1. Remove the glands from the gland plate.

2. Secure the conduit to the gland plate.

3. Feed the cable through the mount, leaving adequate slack for connections (preferably 4 to 6 inches).

4. Secure the gland plate into place on the bottom of the mount.

5. Proceed with the connections in Section 3.2.

3.2 INSTALLING SWITCH BRACKET

Before installing the switch bracket (see Figure 4) into the LWM41 wall mount, the power and video cables must be routed through the mount (as explained in Section 3.1), and the power leads need to be connected to the power switch terminal block on the switch bracket.

To connect power to the switch terminal block, you will need a small standard screw- driver, and a 5/16-inch hex wrench. Perform the following step(s):

1. Connect the leads from the power cable to the switch bracket terminal block as shown in Figure 5. For 120 VAC and 230 VAC, make sure the ground is securely connected. Note Figure 3 and be certain to install chassis GND wire from LWM to the Switch Bracket as indicated in Figure 5.

After the power connections have been made, you are now ready to secure the Switch Bracket into place.

2. With the cable retracted, hook the left securing notch on the switch bracket over the left tab on the LWM and position the switch bracket as shown in Figure 6.

3. Hold and press the switch bracket up against the roof of the arm to depress the bow spring and at the same time rotate the entire switch (as shown), so that the remaining securing notch located on the right side of the switch bracket moves toward the right tab on the arm until the notch and tab engage

4. Make sure the tab clicks into the securing notch of the bracket for a secure fit. The fit should be nice and snug, with no lateral movement, once the unit is in place.

NOTE: In bottom-entry/gland instal- lations, install the BNC connectors to the video out/sync cables only after the cable has been threaded through the glands. The BNC connectors will not fit through the PG-13 glands.

NOTE: The switch bracket will even- tually be mounted to the back end of the mount as shown in Figure 6. To preposition the bracket for mounting (after performing step 1), move the bracket into the arm while extracting the power cable back out of the mount. If the cable cannot be re- tracted in this manner, push it into the cavity behind the hinge base.

NOTE: The power connector clicks and locks into place. After making the connection, turn the Power Switch ON. The power LED on the front of the LRD should be LIT.

Do not use a gland sealing compound at this time. You may need to slide the ca- bling back and forth through the glands during installa- tion.

3.3 INSTALLING RECEIVER MOUNTING HARDWARE

The receiver box mounts to the inside of the mount arm access panel by setting over an anchor stud and thumbnut. When installing the anchor, thumbnut and ap- propriate washers to the studs on the access panel, make sure the hardware is positioned correctly as shown in Figure 7.

1. Install the receiver mounting hardware as shown in Figure 7. Using a supplied flat washer, tighten the 5/16 Hex anchor on the smaller stud located near the inside center of the access panel.

2. Install the supplied nylon washer on the longer stud (located toward the front of the access panel) and turn the supplied knurled thumbnut until the threads of the stud are exposed. The receiver is now ready to be installed.

3.4 INSTALLING THE RECEIVER/DRIVER BOX

To install the receiver/driver box into the LWM41 Legacy wall mount arm, perform the following steps.

1. BEFORE MOUNTING THE RECEIVER/DRIVER BOX TO THE ACCESS PANEL ON THE LWM, CONNECT ALL APPLICABLE CABLES (Video, Alarms, Aux) and the Switch Bracket power connector to the rear of the LRD41 receiver/driver box (see Figures 2, 6 and 7).

2. Mount the receiver/driver box to the access panel by simply aligning the two (2) mounting holes on the bottom of the receiver/driver box with the anchor and thumbnut hardware on the access panel (see Figure 7).

3. After aligning the mounting holes/studs, simply slide the receiver/driver box down over the anchor and thumbnut and attach the box securely.

4. Tighten the locking thumbnut on the forward-most stud to secure the box into place. Make sure the thumbnut is very tight.

NOTE: Once the box is mounted, you cannot see the rear RECEIVER/ DRIVER connectors; however, once you are familiar with the connector types and locations, you should be able to attach the connectors located on the rear of the RECEIVER, after the box is mounted (steps 2, 3, and 4) rather than before.

Pelco Manual C557M (10/99) 15

3.4.1 Pan/Tilt Connection

After the receiver/driver box has been installed to the access panel with the proper connections made as previously noted, the Legacy 37-pin, pan/tilt connector can be connected to the receiver/driver box. With the 37-pin connector, all enclosure, accessory, camera video (as well as Camera Sync), lens and P/T connections are made.

NOTE: REAR PANEL connections should be made (as explained in Sec- tion 3.4, step 1), before mounting the receiver/driver box to the access panel on the LWM.

NOTE: The LRD41 series of receiver/ drivers accommodates an additional electrical (coax) connection to the camera for Camera Sync, which is necessary when multiple cameras re- quire frame synchronization. If used, this cable should also be connected before mounting the receiver/driver box to the access panel on the LWM.

4.1 FEATURES

4.1.1 Control Without Video

With this feature, the receiver/driver is capable of detecting Coaxitron commands from the controller when no video signal is present. Control without video is mainly desired for the auxiliary function.

4.1.2 Transient Suppression

Transient suppression circuitry which has been designed into the LRD41C21/22-* receiver/driver reduces the chance of interrupted operation or damage to the receiver/driver due to voltage spikes on the power, video and signal lines. Tran- sient suppression does not imply lightning suppression.

18 Pelco Manual C557M (10/99)

4.3 PREPOSITIONING

The Legacy Pan and Tilt utilizes linear taper precision potentiometers as the position feedback sensors. This feedback voltage is fed to the receivers micro- controller where it is digitized and stored on nonvolatile memory chips. Each receiver can store up to 64 preset positions for LRD41C models. The first eight presets for either series are tied to the eight alarm contacts in the receiver (see Figure 10).

4.4 ALARMS

The LRD41C21/22-* support eight alarm inputs and one alarm output. If multiple alarms are activated, the receiver will sequence between the alarm presets. Up to eight presets can be activated by alarm contacts connected to the receiver. Any of these alarm inputs would activate an external device through an open collector output.

4.5 AUXILIARY FUNCTIONS

The LRD41C21/22-* is capable of operating up to two remotely activated auxiliary functions. Aux 3 is not available. Aux 4s logical output is dedicated to wiper control inside the Legacy enclosure.

Figure 10. Preposition Alarm Wiring

NOTE: The Alarm Out sig- nal (capable of 25 mA sink- ing maximum) is intended for logic circuits or other low- power devices. If you connect a device that draws more cur- rent than the maximum al- lowed, you could destroy the output circuitry. If you wish to operate a device that requires greater current, then interface it with a relay.

4.6 AUTO/RANDOM SCAN OPERATION

Auto and random scan can be operated in either of two ways, depending on the type of control unit you have. One method involves using the Auto/Man switch (or keys) if your control unit has these functions. The other method involves setting presets.

Auto/Man Switch The Random Scan and Auto Scan functions are controlled by the same momentary switch on the control panel labeled Auto and Man. The first activation of the switch to the Auto position will put the pan/tilt into Random Scan. In Random Scan operation, the pan/tilt will travel between the preset limits with a random scan period of about 2 to 30 seconds, and a random dwell period of be- tween 2 to 30 seconds.

At the completion of a dwell period, another random scan period is started. The direction of this scan period is also randomly determined. When a pan limit is reached, scan direction is reversed automatically.

A second activation of the Auto switch will put the pan/tilt into continuous duty Auto Scan (limit switch to limit switch). After approximately 1/2 hour of auto scan, the circuit will reset to random scan. Commanding Auto while in Random mode causes a shift to Auto mode and starts the 1/2-hour timer. Similarly, commanding Auto while in Auto mode causes a shift to the Random mode and zeros the 1/2-hour timer.

Presets Auto and random scan also can be started by programming presets. The presets will work only when your system is configured for Extended (32-bit) Coaxitron mode.

Refer to your controller documentation for programming presets.

Preset 96 stops a scan.

Preset 97 starts random scan.

Preset 99 starts auto scan.

Advantages of Random Scan:

Because scan direction, scan period and dwell period are unpredictable, un- authorized activities or intrusions are discouraged.

Because of the reduced duty cycle, gear train wear, cable fatigue, drive motor wear and temperature rise are reduced. These factors all contribute to higher system reliability and increased equipment life.

4.7 TEST LOCAL CONTROL TLC

This feature allows you to connect an LRD41TLC Test Local Control (TLC) module to the receiver/driver to test the control of pan, tilt and lens functions locally. This is convenient for positioning limit stops, backfocusing, and troubleshooting the instal- lation. The TLC module also allows positioning of the camera locally.

To use the TLC module:

1. Turn receiver OFF and plug the 16-pin connector from the TLC module into the TLC connector on the receiver/driver (refer to Figure 1). Turn the receiver ON to activate TLC functions.

2. Hold down the keys on the TLC module to operate the pan, tilt, and camera functions.

3. Upon completion, detach the TLC; the LRD unit will revert to its previous op- erational configuration.

NOTE: The receiver does not have to be connected to other control equipment in order for the TLC mod- ule to work. If the receiver is con- nected to other control equipment, the TLC module will override any trans- mitter control signals from other con- trol equipment.

Pelco Manual C557M (10/99) 21

4.8 PAN/TILT VOLTAGE SETTINGS

Refer to Table A for information regarding pan/tilt voltages.

4.9 RESET

If you experience control difficulties with your system, programming preset 94 will reset the system. The receiver will go through a power-up routine and restart opera- tion. Any presets programmed into memory will be retained. Refer to your controller documentation for programming presets. The preset will work only when your sys- tem is configured for Extended (32-bit) Coaxitron mode.

4.10 LRD41 ADDRESS SELECTION SWITCH SETTINGS

NOTE: The LRD address selec- tion switch is located on the left side panel of the unit when looking at the unit from the 37-pin connection end. The ten position dip-switch, of which only the first 5 positions are used for P-type protocol, gives a total of 32 addresses (see Table C for D-Type protocol where the first 8 switch positions are used for ad- dressing, giving a total of 255 ad- dresses).

5.0 TROUBLESHOOTING

Symptom: Front panel power LED is not lit; unit not responsive to PTZ con- trol commands (controlling Matrix system assumed to be good):

1. Disconnect the unit from its power source (switch bracket power input connector).

2. Remove the LRD fuse (F1, power input) and verify whether or not the fuse is good.

3. If it is open, replace it with one of the correct value.

4. Restore power.

5. Unit should reconfigure itself and once completed, the power LED on the front panel should remain lit. Resume operation.

Symptom: Front panel power LED is lit, but enclosure accessories are inoperative (heater, blowers or defrosters):

1. Disconnect the unit from its power source.

2. Check the enclosure fuse (F2) and verify that it is good and is of the correct value.

3. Replace the fuse if it is open or if the value is incorrect.

4. Restore power, check unit and resume operation.

or

5. If applicable accessory is still not operating, then. . .

a. Substitue a known good unit, if possible, in place of the suspected bad one.

b. If, after substitution, operation returns to normal, then the unit replaced by the substitution is defective. Return it to the factory for repair.

c. If, after substitution, operation is still abnormal, then the unit replaced by the substitution is OK. Proceed to check for the problem elsewhere; i.e., check for bad or frayed cables or for incorrect wiring, etc.
