B. Mounting the LDB-2 Control Module
The control module is designed to be wall mounted using either screws
or the included foam tape.
Step 1. Remove the cover from the control module.
Step 2. Mount the unit on a wall, using either screws or the included foam
tape. Make sure there is easy access to the internal terminal
block. The internal board of the control module can be rotated
exposing the two mounting holes in the chassis.
Step 3. Once mounted, swing the board back into position and attach wires.
Step 4. Replace cover making sure wires protrude through rectangular wire
pass-through.
Note: For information on installing the BLK-1A with the E-1600-20A see
Other Applications.

A. Adjustable Relay Closure Time Out
The time out POT (see diagram to the right) can be adjusted from 2 to 6 seconds.
Turn the time out POT counter clockwise to decrease the closure time. Turn it clock-
wise to increase the closure time. When monitoring for ring, turning the time out POT
fully clockwise will allow the relay closure to be maintained (strobe will continue flash-
ing) during the entire off time of the ring signal. When monitoring for loop, the relay
closure will be maintained while off-hook and will time out following an on-hook (strobe
will continue to flash until time-out occurs).
B. Relay Contact Selections
The auxiliary relay contact located at terminal pins 5 & 6 can be used to control other
equipment. It can be set for normally open (N/O) or normally closed (N/C) by reposi-
tioning JP1 (see diagram to the right). Note: JP2 should be left in the normally open
position (N/O
