The ICVC has a stop button, an alarm light, four buttons for
logic inputs, and a backlight display. The backlight will auto-
matically turn off after 15 minutes of non-use. The functions of
the four buttons or “softkeys” are menu driven and are shown
on the display directly above the softkeys.
The viewing angle of the ICVC can be adjusted for opti-
mum viewing. Remove the 2 bolts connecting the control panel
to the brackets attached to the cooler. Place them in one of the
holes to pivot the control panel forward to backward to change
the viewing angle. See Fig. 11. To change the contrast of the
display, access the adjustment on the back of the ICVC. See
Fig. 11.
English is the default language.
Three other programmed languages are available as options:
Chinese
Japanese
Korean
NOTE: Pressing any one of the four softkey buttons will acti-
vate the backlight display without implementing a softkey
function.
INTEGRATED STARTER MODULE (ISM) — This mod-
ule is located in the starter cabinet. This module initiates com-
mands from the ICVC for starter functions such as starting and
stopping the compressor, condenser, chilled water pumps, tow-
er fan, spare alarm contacts, and the shunt trip. The ISM moni-
tors starter inputs such as line voltage, motor current, ground
fault, remote start contact, spare safety, condenser high pres-
sure, oil pump interlock, starter 1M, and run contacts. It shuts
down the chiller if communications with the ICVC are lost.
The ISM can also act as the interface for PIC II to the VFD
controller.
The ISM module directly measures current and voltage for
each phase. Calculation of power factor, power in kilowatts,
and energy in kilowatt hours is performed by software in the
ISM for constant speed starters only. All of these values are
transmitted to the ICVC on the SIO (sensor input/output) com-
munications bus. The ISM software also defines conditions for
transition for different starter types, and it integrates I
2
t in mon-
itoring motor overload.
CHILLER CONTROL MODULE (CCM) — This module is
located in the control panel. The CCM provides the input and
outputs necessary to control the chiller. This module monitors
refrigerant pressure, entering and leaving water temperatures,
and outputs control for the guide vane actuator, oil heaters, and
oil pump. The CCM is the connection point for optional de-
mand limit, chilled water reset, remote temperature reset, re-
frigerant leak sensor and motor kilowatt output.
