9. To Processindicatestheprocesscoolinguid(waterorwater/glycol)pressure.
10. When the compressor is turned off, the instrument will wait 3 minutes before
turning it back on regardless of the To Process temperature or Setpoint.
 Ifalowpressureoroptionallowowfaulthasoccurred,thecontrolwillattempt
to turn the compressor back on after 3 minutes. If the fault condition remains, the
compressor will not restart and the control will retry after 1 minute. The sequence
will repeat 3 times then the system will lock-out and the unit must be powered off/
on to restart the unit.
If a high pressure fault occurs the fault must be acknowledged by pressing the
start button before the system will attempt to restart.
11. Under normal conditions (no fault conditions, compressor has been off for
3 minutes) the instrument will turn on the compressor when the To Process
temperature is above the Setpoint. The instrument will engage the capacity
control system (digital unloading or hot gas bypass) when the To Process
temperature is below the Setpoint by no more than 3 degrees.
Units equipped with a digital scroll compressor (includes a “D” in the model
number such as MGD-10A) will operate in the unloaded state for a maximum of
50 seconds out of every 60 seconds.
The instrument will turn off the compressor and capacity control system when the
To Process temperature is 4 degrees or more below the setpoint.
C. STOPPING THE UNIT
1. Press the red O button.
2. If the compressor is running when the off button is pressed the refrigeration
systemwillstopbutthepumpwillcontinuetocirculateuidforabout30seconds
to carry away residual cooling.
3. Pressing the stop button twice will immediately shut down the entire chiller
including the process pump.
4. If the compressor is not running when the off button is pressed the chiller and
pump will shut down.
