Wiring a Contactor
The eight onboard relays are rated at 240VAC@5AMPs (110VAC@10AMPs) switch-
ing capacity. Contactors should be used for devices drawing current loads higher
than relay specification. See figure 3.22 for contactor wiring.
Note:
- Contactor must meet the electrical requirements of the load.

Test Relay Outputs:
Apply power to 5X00. Verify device activates at relay test. See Relay Test - page 134.
Note:
Entering the relay test menu turns off any active relays and disables any sensor, aux,
and timer system relays from energizing regardless of value or condition. Systems
are not reset when the Relay Test menu is exited. To reset systems after exiting the
Relay Test menu, power cycle the 5X00.
Step 7 Wire Aux Inputs (Non Temperature)
The 5X00 has six (6) auxiliary inputs. All 6 auxiliary inputs can be used for digital
(open/closed dry contacts) or analog (0-1VDC; 0-5VDC, or 4-20ma) inputs. Auxil-
iary inputs 3, 4, 5, and 6 can be configured for a temperature sensor. See Temperature
Probes - page 54 for wiring directions. Aux inputs can be used for a variety of
applications including: level switch, pressure switch, and/or an external instrument
with an analog recorder output. Aux input wires are terminated at location L and/
or M on I/O Board - figure 3.23. (See 5X00 I/O Board wiring diagram on inside of
front panel for identification of aux system number and pin position.) See Digital
Input example - figure 3.24, and Analog Input example - figure 3.25. (Common
lettering references are used for both 5400 and 5500 models).
Notes:
- All aux inputs have input protection, the maximum input voltage should not
exceed 6 VDC.
- Analog systems will not monitor and/or alarm properly if the device that is
installed and configured operates outside the configured analog range.
- For proper digital input operation, use low impedance switches and wiring.
The total resistance should not exceed 200 Ω (ohms).
Directions to Wire Aux Inputs (Non Temperature Inputs)
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant d’effectuer
un câblage quelconque.
1. Perform steps 1-4 of 5X00 installation and steps 5 -6 as required for the
application.
2. Open front panel - page 42 .
3. Feed auxiliary device cable(s) through drilled hole in rubber grommet
to locations L and/or M. The terminal strip is removable.
CAUTION : Run high and low voltage cables through separate bulkhead and
conduit.
4. For Aux 3, 4, 5, & 6 use the terminal strip located at L, using (+) termi-
nal strip port for non ground wire and (-) for ground wire. For Aux 1
and 2, use terminal strip located at M. “G” pin is the common ground
for Aux 1 and 2.
