11.16.4 Indication of a service warning

A service warning is an exceptional event and requires the attention of the operator/service technician. Such a warning
will usually not stop the chiller (unless a high dew point parameter was adjusted to stop the chiller).
When a service warning is active, the
stored and the LED is continuously on.
In both cases the display shows the dew point temperature and the service warnings which are active or which are no
longer active but not yet reset.
Service warnings are not automatically reset (except for
To RESET the service warning, simultaneously press the
warning will be reset. Service warnings which are still active continue to be indicated by the flashing
NOTE: the operator/service technician must check the chiller and eliminate the problem that led to the
activation of the service warning.
Service warning
PF1 – Probe 1 failure: failure temperature probe 1
PF2 - Probe 2 failure: failure temperature probe 2
PF3 - Probe 3 failure: failure temperature probe 3
HdP – High dew point: dew point too high, higher than the adjusted HdA value.
LdP – Low dew point: dew point too low
Setting T1< -1°C (30°F) delay five minutes / reset T1> 0°C (32°F)
drn - Drain: failure condensate drain (opening of the DRN contact – if an electronically level-
controlled condensate drain is installed – see electric diagram)
SrV - Service : maintenance service time expired SrV
dt – Outlet temperature: compressor outlet temperature (probe T4) outside the normal values
but within the safety limits
Setting T4> 90°C (194°F) delay three minutes / reset T4< 85°C (185°F)
HCP – High condensation pressure: condensation pressure (transformer HP) outside the
normal values but within the safety limits
Setting HP> 28barg (406psig) delay three minutes / reset HP< 25barg (363psig)
NOTE: when the chiller is switched on but no system pressure is applied, the
