Note: If the chiller is operating in
a limit mode (current limit,
condenser limit, evaporator
limit, and so forth), the limit
operation has priority over all
DynaView

manual modes of
operation.
On each CH530 power-up, the
inlet guide vanes are driven full
closed to recalibrate the zero
position (steps) of the Stepper
motor vane actuator.
Motor Temperature Sensor
Module
The motor temperature module
1A26 connects using unit wiring
to the three motor winding
temperature sensors. This
module is located in the control
panel where the module is
connected to the IPC bus.
Temperature Sensors
Evaporator entering 4R6
Evaporator leaving 4R7
Condenser entering 4R8
Condenser leaving 4R9
Oil temperature 4R5
Outdoor air 4R13
Evaporator saturated refrigerant

Probe Operating Temperature
Range -40 to 121°C
Accuracy± 0.250°C over the
range - 20 to 50°C ± 0.50°C over
the range -40 to 121°C
Starter Module
In the hierarchy of modules the
Starter module 2A1 (1A23 when
customer-supplied starter
specified) is second only to the
DynaView
™
.
The starter module is present in
all starter selections. This
includes Wye Delta, Across the
Line, and Solid State whether
remote unit mounted or supplied
by others. The starter module
provides the logic to provide the
motor protection for current
overload, phase reversal, phase
loss, phase imbalance, and
momentary power loss.
