2.13  Digital operation 

A Digital unit is able to operate in a part-load mode. Part-load operation is achieved by loading and 
unloading of the Digital scroll compressor for certain periods of time (time cycles). The cycle of time 
can  be  chosen  between  10  and  30  seconds.  Example:  if  the  time  cycle  is  20  seconds  at  50%  of 
capacity  request,  the  compressor  will  run  for  10  seconds  loaded  and  10  seconds  unloaded.  For 
proper commissioning of the Digital unit the following diagram must be considered: 

 

Figure 13: Digital operation 

The  regulation  starts  when  the  suction  pressure  (

AI1

)  increases  and  reaches  the  value 

(SP-PB/2+(PB*PMI)/100) 

or 

(C16-C17/2+(C17*C24)/100).  Within  the 

adjustment  range 

(SP-PB/2~SP+PB/2) or (C16

–C17/2 ~ C16+C17/2) the Digital scroll compressor is activated in PWM 

mode according to the value of the control variable. 

When the pressure is higher than (SP + PB/2) or (C16 + C17/2) then the TRIAC output is at maximum 
capacity. When the pressure is lower than (SP + PB/2) or (C16 + C17/2) but higher than (SP-PB/2) 
the  Digital  Scroll  compressor  modulates  the  capacity  according  to  the  proportional  band.  If  the 
pressure is lower than (SP-PB/2)/ (C16-C17/2) the Digital Scroll compressor switches off. 

NOTE: When the digital valve on the compressor is discharged the compressor is loaded. 

NOTE: At start-up the valve is energized for Sut/C20 start-up time, ie, time interval with the 
digital valve energized before regulation starts. It ranges from 0 to 10 seconds. 

2.14  Pump-down 

– General 

 

CAUTION 
System  pressure  below  atmospheric  pressure!  Compressor  damage!

 

Never  operate  the  system  below  atmospheric  pressure.  There  is  a  risk  of 
malfunction  of  the  controller  in  deep  vacuum  operation  which  can  cause 
compressor damage. 

 

Pump-down functionality is provided by the XCM25D controller for ZXME and ZXLE units only. It is 
not released for Digital units ZXDE. 

NOTE: Depending on the compressor and/or system design an increase of suction pressure 
is possible when the unit stops. Therefore, pump-down operation requires higher differences 
between  cut-in  and  cut-out  setpoints.  These  values  must  be  adjusted  according  to 
application. 

2.14.1  External pump-down 

– Without XCM25D integration (not available on ZXDE units) 

The  easiest  solution  for  pump-down  is  to  install  a  solenoid  valve  in  the  liquid  line  (not  part  of  the 
standard delivery) and to control it directly with the room thermostat or other external devices. The 
settings on the unit for compressor cut-in and cut-out (

C01

 & 

C02

) can easily be adjusted for pump-

down.  The  disadvantage  of  this  easy  solution  is  that  the  controller  is  not  informed  that  there  is  a 
solenoid valve installed and therefore some protection features of the controller, eg, maximum pump-
down time in case of blocked solenoid, will not work. 

2.14.2  Pump-down by the unit controller (not available on ZXDE units) 

In case of pump-down by the unit controller (available only for ZXME and ZXLE units) the user needs 
to install a solenoid valve in the liquid line (not part of the standard delivery). In addition to the liquid 
line solenoid valve a digital input signal from a room thermostat or a case temperature sensor must
