Circuit Management: Saturation Or Balancing; Maximum Operation Time Of The Compressor; Pump Down - Emerson Dixell iChill IC200D EVO Series Installing And Operating Instructions


step 2: the compressor is switched off and is activated the compressor with higher capacity

step 3: both compressors are activated
The regulation is a steps; if two compressors with different weight are configured, 3 steps are available.

19. CIRCUIT MANAGEMENT: SATURATION OR BALANCING

In case of 2 circuits machine it is possible to decide how to balance the circuits:

it is possible to switch on all compressors of the circuit before switch on a compressor of the
other circuit (saturation)

it is possible to switch on first compressor of a circuit and then the first compressor of the
other circuit (balancing)
CIRCUIT SATURATION
CO15 = 0
If the machine has 2 compressors in the circuit 1 and 2 compressors in the circuit 2, the sequence of
activation is:
st
1 compressor circuit 1 2
CIRCUIT BALANCING
CO15 = 1
If the machine has 2 compressors in the circuit 1 and 2 compressors in the circuit 2, the sequence of
activation is:
st
1 compressor circuit 1 1

20. MAXIMUM OPERATION TIME OF THE COMPRESSOR

In the event that in a circuit there are more compressors but only one is switched on, after the operation time
CO72 the compressor is switched off and another compressor (according on the configuration, in function of
operating hours or number of switching on) is turned on.
CO72 Tempo massimo di funzionamento continuativo compressore
CO98 Simultaneous operation time of the compressors for rotation

21. PUMP DOWN

21.1 PUMP DOWN WITH LOW PRESSURE SWITCH OR PUMP DOWN PRESSURE
SWITCH
CO36 = 1 Pump down enabled during the switching off (low pressure switch or pump down switch)
Before turning off the last compressor, the solenoid valve is closed; the compressor works until the pressure
switch is activated or after a maximum time CO39; in this case an alarm is displayed (b1PH or b2PH) but the
machine continuous to work as normal condition.
If the alarm occurs more than AL21 times per hour, the Ichill generate a manual alarm.
Low pressure alarm (when the low pressure switch is used) is disabled for AL02 time after valve activation
(AL02=0 the alarm is disabled when the compressor is OFF).
When first compressor of the circuit is switched on, the solenoid valve is switched on 1 seconds before it.
CO36 = 2 Pump down enabled during the switching off and switching on (low pressure switch or
pump down switch)
