Table 13: Defrost parameters
* G17 parameter >> Three defrost modes are available:
▪
G17 = EL
→ Defrost through electrical heater
Compressor Off
▪
G17 = pulse
→ Pulse / natural defrost
Compressor Off
** G23 parameter >> Defrost interval mode:
▪
G23 = nu (0)
→ Defrost functionality not used
▪
G23 = in (1)
→ Defrost in intervals G18
▪
G23 = rtC (2)
→ Enables defrost for rtC (real time clock), allows timing of defrost cycles
with G28
– G41
*** G24 parameter >> Display during defrost:
▪
G24 = dEF (0)
→ Display shows "dEF" for defrost
▪
G24 = SET (1)
→ Display shows "G02" parameter value = Case temperature setpoint
▪
G24 = it (2)
→ Display shows display case temperature value
▪
G24 = rt (3)
→ Display will stay in standard operation
**** G42 parameter >> Evaporator fans function:
▪
G42 = cn (0)
→ Will switch On and Off with the compressor, Off during defrost
▪
G42 = On (1)
→ Fans On, even if the compressor is off, Off during defrost
o
After defrost, there is a timed fan delay allowing for drip time, set by means of the
"G55" parameter.
▪
G42 = cy (2)
→ Fans will switch On and Off with the compressor, On during defrost
▪
G42 = Oy (3)
→Fans will run continuously also during defrost
Manual defrost
Please check settings for evaporator fans. The XCM25D controller is able to control the evaporator
fan.
NOTE: For additional features please contact your local Application Engineering
representative.

CAUTION
Low refrigerant charge! Compressor damage!
Never energize the
unit/controller without minimum refrigerant system charge. There is a risk of
malfunction of the controller in deep vacuum operation which can cause
compressor damage.
