3.
Connect wires per WIRING DIAGRAM as follows: BLACK (Hot) wire to BLACK lead of device, and WHITE (Neutral) to White lead of device.
Twist strands of each lead tightly together and, with circuit conductor push firmly into appropriate wire connector. Screw connector on clockwise
making sure that no bare wire shows below the connector. Secure each wire connector with electrical tape.
4.
Using a small screwdriver, set the Black Number Code and Red Letter Code dials to the desired address by gently turning the indicators to
the proper positions
(refer to Figure 2 and the examples in the Testing section)
.
5.
Mount Cat. No. 16400 in wallbox using the screws provided.
NOTE:
Ensure that connector is located at the bottom of the device when mounting
(refer to Figure 2)
.
6.
Install the desired Cat. No. 16450 keypad on the Controller. Place the keypad tab under the Controller strap. Align the keypad pins with the
Controller connector. Press down gently until the keypad is fully seated on the Controller.
CAUTION:
DO NOT
ATTEMPT TO INSTALL ANY OF THE CAT. NO. 6450 OR 6319 KEYPADS - THEY ARE NOT INTERCHANGEABLE
WITH CAT. NO. 16400.
7.
Mount wallplate.
8.
Restore power at circuit breaker or fuse.
INSTALLATION IS COMPLETE.
SCENE PROGRAMMING (Cat. Nos. 16450-SD and 16450-S)
1.
Using a small tool, depress the programming button on the Cat. No. 16450 face until the RED LED’s flash. You are now in the
programming mode.
2.
At each local dimmer (Cat. No. 6343 or 16383) or switch (Cat. No. 16293), adjust lights to the desired level.
3.
At the Cat. No. 16400/16450, assign a button to the desired scene then press the left side of that button to program until the LED stays ON
and no longer flashes.
NOTE:
To remove a scene, press the right side of the button and the scene will be removed.
4.
Repeat steps 2 and 3 to program each additional scene until all of the scenes are set (LED’s are all ON and are no longer flashing).
5.
Depress the programming button to leave the programming mode and restore normal operation.
TO OPERATE (Cat. Nos. 16450-1, 16450-1A, 16450-2, 16450-2D, 16450-4, 16450-4A and 16450-4D ONLY)
Pressing the left side of the button will transmit ON, ALL ON, or BRIGHT commands, regardless of which keypad is being used. Pressing the
right side of the button will transmit OFF, ALL OFF, or DIM commands.
When transmitting an ON/ALL ON command, the LED will blink while the signal is being transmitted and will stay ON when the signal has
completed the transmission. When transmitting an OFF/ALL OFF command, the LED will blink while the signal is being transmitted and turn
OFF when the signal has completed the transmission. If there is a BRIGHT/DIM function on the keypad, pressing the BRIGHT or DIM button will
cause the LED’s on the face of the keypad to flash and will remain flashing until the button is released.
TO OPERATE (Cat. Nos. 16450-SD and 16450-S ONLY)
Pressing the left side of the button will transmit SCENE ON or GROUP BRIGHT commands, regardless of which keypad is being used.
Pressing the right side of the button will transmit SCENE OFF or GROUP DIM commands.
When transmitting a SCENE ON command, the LED will blink while the signal is being transmitted and will stay ON when the signal has
completed the transmission. When transmitting a SCENE OFF command, the LED will blink while the signal is being transmitted and turn OFF
when the signal has completed the transmission. If there is a GROUP BRIGHT/GROUP DIM function on the keypad, pressing the BRIGHT or
DIM button will cause the LED’s on the face of the keypad to flash and will remain flashing until the button is released.
TESTING
Press the keypad rocker(s) to confirm that the load or loads are turned ON and OFF within two seconds of signal transmission. If the Cat.
No. 16400 Controller appears to be functioning improperly or operates erratically, read the following paragraphs, then refer to the Perfect
Performance Checklist.
When using a multiple-rocker keypad, the top rocker transmits as per the letter/number code set on the Controller. The next rocker down
transmits to the same letter, next number address as set on the Controller, and so on.
Examples:
1.
A Cat. No. 16450-4 set at A3: top rocker controls the A3 address, the next rocker controls the A4 address, and so on.
2.
A Cat. No. 16450-4 set at B15: top rocker controls the B15 address, the next rocker controls the B16 address, the next rocker controls the
B1 address, and the last rocker controls the B2 address.
An ALL ON/OFF rocker controls all DHC modules set to the same letter code as on the Cat. No. 16400 Controller. ALL ON only turns ON
lighting modules. ALL OFF turns OFF all modules set to the same letter code.
PERFECT PERFORMANCE CHECKLIST
If the Cat. No. 16400 Controller appears to be functioning improperly proceed with the following steps:
1.
Confirm that the Controller is wired exactly as shown in the wiring diagram.
2.
Confirm that the module is being supplied from a 120V, 60Hz AC source ONLY.
3.
Confirm that the load being controlled is in proper working order. Local switch, ON (check for burned-out bulbs, etc.).
4.
Confirm that the Controller is powered and is set to transmit commands to the same letter and number code on modules.
5.
Confirm that the Cat. No. 16450 keypad is installed properly.
NOTE:
If the Controller still does not operate properly after following steps 1-5, proceed with diagnostic steps 6 and 7.
6.
Set the Controller to transmit address P1. Using a Cat No. 6386 Signal Strength Indicator plugged in on the same branch circuit as the
Controller, confirm that the Controller is transmitting a minimum reading of 2 volts of command signal at the HI-RANGE setting. If the signal
strength is less than 2 volts, have the Controller checked.
7.
Check for adequate command signal at the Cat. No. 16400 location as follows:
A.
Plug the Cat. No. 6385 Signal Test Transmitter into a receptacle on the same circuit as the Controller.
B
. Using the Cat. No. 6386 Signal Strength Indicator at the 16400 location, check the command signal amplitude. Signal strength must be
100mV minimum. If there is less than 100mV of signal present, it may be necessary to couple both legs of the 120/240 Volt power
service at the entrance panel using Cat. No. 6299 Signal Bridge.
C.
If the Yellow ERROR CONDITION indicator is lit, there is electrical “noise” present on the AC line which is interfering with proper
module operation. The source of the noise must be identified and either filtered out or eliminated
(See Technical Manual)
.
8.
Confirm that you have a recent version of the DHC System Coupler/Repeater. To do this, follow steps 1-3 in the Scene Programming
section. If the LED’s continue to flash after a scene button is pressed in step 3, you must upgrade your DHC System. A Repeater/Coupler
is recommended in all DHC systems for maximum signal.
9.
