NOTE: DCCT power supply (±15V) is provided only for analog input configurations with bi-voltage inputs; i.e. List 120 and
List 125. DCCT power output is protected against short circuits and is able to power four DCCTs.
CAUTION: to reduce risk of fire, use only #26 AWG (0.14mm²) or larger wire.
NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
Custom configurations may be detailed within the Argus power system documentation package.
5.8 Relay Outputs
Terminals 37 to 60 provide 8 Form C contacts (NO, COM and NC) for extending various alarm or control signals.
Each relay output can be wired for NO and/or NC operation during an alarm or control condition. See Figure 7.
Figure 7–Showing relay connections in the de-energized state
Relays can be programmed to energize or de-energize during an alarm condition (see Software manual). When
the CXC reset button is pressed or power is lost, all relays de-energize.
Relay contacts 1-8 are high capacity and intended to be used for controlling LVD contactors.
5.8.1 System Fail Relay
Terminals 61 to 63 provide connections for a system (supervisory) fail relay. This fail-safe relay (i.e. it is de-
energized during an alarm condition) can be wired for NO or NC operation.
5.8.2 LVD Control
The LVD control functions can be hardwired directly from the assigned relay output pins to the LVD contactor
panel. See Controls Menu Defaults in the Software manual.
5.8.3 CEMF Cell Control
The CEMF control function can be hardwired directly from the assigned channel in to the CEMF cell controller
panel. See Controls Menu Defaults in the Software manual.
5.8.4 Optional Relays and Outputs
Eight relays and outputs may be added to the CXC (panel and rack models) with the purchase of an optional
expansion board (see List Options at the front of this manual).
