COMMENTS
Remote contact 1 status
This contact is used to start (contact closed) and stop (contact open) the chiller. It is only valid, if the unit is in the remote operating
control (rEM) mode.
Remote contact 2 status
This contact is used to select a cooling only setpoint, if the unit is in cooling mode and in the remote operating control (rEM) type.
Contact open = csp1
Contact closed = csp2
Remote contact 3 status
This contact is used to select the heating or cooling mode, only if the unit is in the remote operating control type.
Contact open: unit in cooling mode
Contact closed: unit in heating mode
Remote contact 4 status
This contact is used to select the second condensing setpoint or the heat reclaim mode (for a heat reclaim unit), only if the unit is in
the remote operating control type.
Contact open = unit uses the normal condensing setpoint and is in normal mode (no heat reclaim)
Contact closed = unit uses the heat reclaim setpoint and is in heat reclaim mode.
Remote contact 5 status*
If this contact is closed, it permits limiting the unit demand, based on the demand limit setpoint, if the demand limit method by
contact has been selected.
Water flow and customer interlock control contact status*
Opening of this contact shuts the unit off or prevents its start-up and generates an alarm. It is used to control the water circulation.
Water pump operation status. If the contact opens when the evaporator pump has received a command to operate, this trips a
pump failure alarm.
Condenser water flow control. Controls the condenser water circulation.
Control box thermostat and phase reversal interlock status*. Opening of this contact shuts the unit off or prevents its start-up
and generates an alarm.
External 0-10 V d.c. signal. This signal from an external source can be used (based on the configuration) for the reset or demand
limit function of the unit.
DESCRIPTION.
Compressor status
b1 = compressor A1
b2 = compressor A2
b3 = compressor A3
b4 = compressor A4
This item permits display of the compressor status in circuit A. It also permits independent testing. In test mode the direction
arrows permit successive display of 0001, 0010, 0100 and 1000, so as to in turn force authorisation of each output.
Compressor status
b1 = compressor B1
b2 = compressor B2
b3 = compressor B3
b4 = compressor B4
This item permits display of the compressor status in circuit B. It also permits independent testing. In test mode the direction
arrows permit successive display of 0001, 0010, 0100 and 1000, so as to in turn force authorisation of each output.
Capacity reduction status, circuits A & B
b1 = capacity reduction A1
b2 = capacity reduction B1
This item permits display of the capacity reduction status in circuit A. It also permits independent testing.
Fan contactor status/test, circuit A
b1 = fan contactor assembly 1
b2 = fan contactor assembly 2
b3 = fan contactor assembly 3
b4 = fan contactor assembly 4
This item permits display of the fan stages. It also permits independent testing. In test mode the direction arrows permit
successive display of 0001, 0010, 0100 and 1000, so as to in turn force authorisation of each output.
