B. INSTRUMENT OPERATION
1. To start the unit, toggle on the illuminated ON/
OFF SWITCH. The pump will start and the chiller control will
begin temperature control operations.
2. To select setpoint temperature, press and hold the UP
ARROW or DOWN ARROW keys until the desired set point
temperature is displayed in the TEMPERATURE WINDOW.
The default range for the setpoint temperature is 48° - 70°F
or 9° - 21°C.
3. The setpoint temperature can be displayed by pressing
the UP ARROW or DOWN ARROW keys. The setpoint
temperature will be displayed for 5 seconds.
4. 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 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. This
sequence will repeat 3 times then the system will lock-out
and the unit must be powered off/on to restart the unit.
5. Under normal conditions (no fault conditions, compressor
has been off for three 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 (M1D-5A,
M1D-5W, M1D-10A, M1D-10W, M1D-15A, M1D-15W) 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.
