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.
C. CONTROL INSTRUMENT COMPONENTS
1. ILLUMINATED ON/OFF SWITCH: This rocker switch starts or stops the unit.
Electrical power is supplied to the unit when the switch is illuminated.
2. UP ARROW and DOWN ARROW KEYS: Depress and hold this push button to
increase (UP ARROW) or decrease (DOWN ARROW) the setpoint temperature.
If the push button is pressed momentarily the setpoint value is incremented or
decremented by one degree. If the push button is held down the setpoint will
increase or decrease continuously.
3. SETPOINT LOCK OUT JUMPER: This jumper controls whether the user is
allowed to reduce the setpoint below 48°F or 9°C. If the jumper is in position 1
(farthest from the SPL label) the user IS NOT ALLOWED to reduce the setpoint
below 48°F or 9°C. If the jumper is in position 2 (closest to the SPL label) the
user is allowed to reduce the setpoint to 10°F or -11°C.
4. TEMPERATURE DISPLAY JUMPER: If this jumper is in the “F” position, the To
Process and Setpoint temperatures are displayed in Fahrenheit. If the jumper is
in the “C” position, the To Process and Setpoint temperatures are displayed in
Celsius.
5. Probe Calibration: This pot (CALPOT 1) is used to calibrate the probe circuit.
D. STATUS LIGHTS
1. COMPRESSOR: Illuminates when compressor is turned on.
2. CAPACITY CONTROL: Illuminates when capacity control system is turned on.
3. REFRIGERANT FAULT: Illuminates when there is a high pressure or low
pressure fault. Check troubleshooting section of this manual for more details.
High Pressure Fault. If the chiller control detects a high pressure condition it will
immediately turn off the compressor and hot gas bypass.
