Wiring The Relay Module Bottom Terminals; Wiring The Sub Base; Wiring The Sub Base Terminals - Honeywell DBC2000E10 Series Handbook

REMOVE THE RELAY MODULE FROM ITS
SUB BASE AND FIX THE SUB BASE
1. Loosen the M3 fixing screw as shown in Fig. 1 by
about eight turns using a Philips head screwdriver.
2. Take the subbase and cover with both hands and
unfold them gently. Fold the relay module
upwards, the turning point is on the top. Do not
apply excessive force, otherwise damage may
occur.
3. Punch out the needed conduit knockout holes for
the wiring as shown in Figs 1 and 2, and install the
wiring conduit(s).
4. Using the fixing screws, mount the subbase in the
specified position.
Avoid to overtighten the fixation screw on the
front of the device, to avoid damaging the
(Phillips) head of the screw.
WIRING THE RELAY MODULE BOTTOM
TERMINALS
1. For applications with a UV detector, remove the
jumper terminal located at the terminal block on
the bottom of the relay module.
2. For applications using remote communication,
connect communication cable to "BUS" terminal
located at the terminal block on the bottom of the
relay module. In addition, set the communication
address uring the rotary switches at the bottom of
the relay module.

WIRING THE SUB BASE

1. Fig. 2 shows the layout of the terminals on the
subbase, and Figs. 3-1 to 3-3 show examples of
connections to external equipment. Regarding the
wiring to the flame detector, refer to Fig. 4.
2. When using Intermittent Pilot, connect the pilot
valve to Terminal 5. Connect the main valves to
Terminal 7 (Enhanced and Ultimate models:
connect main valve 1 to Terminal 7 and main valve
2 to Terminal 12 for the VPS function)

circuits to electrically safe contacts which may
cause an electrical shock hazard.
Always use cable lugs to attach the wires to the
sub base.
