7.15.4 How a service warning is displayed
A service warning is an unusual event that must recall the attention of operators/maintenance technicians.
Generally it does not stop the dryer (except for a high DewPoint parameter that can be set to stop the dryer).
When the service warning is active the led
flashes. If the service warning is memorized (it tripped but
then it switched off by itself) led
is lighted.
In both cases the display shows the DewPoint temperature and the service warnings that are active or not
active but that have not yet been reset.
Service warnings are not automatically reset (except for
that can be set in auto-reset).
To RESET the service warning press the buttons
log
reset
simultaneously for 3 seconds. Only the memorized
service warning will be reset, whereas the service warning are still engaged will remain displayed and the
led
flashes.
NOTE: the operator/maintenance technician must inspect the dryer and verify/solve the problem that
generated the service warning.
Service Warning Description
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 DewPoint: DewPoint too high, higher than the HdA value set.
LdP - Low DewPoint : DewPoint too low
Set T1< -1°C (30°F) delay 5 minutes / Reset T1> 0°C (32°F)
drn - Drainer : condensate drainer failure (opening of contact DRN – if electronic level
drainer is installed – see electric diagram)
SrV - Service : maintenance service time expired SrV
dt - Discharge Temperature : compressor discharge temperature (probe T4) beyond
normal values, but within safety limits
Set T4> 90°C (194°F) delay 3 minutes / Reset T4< 85°C (185°F)
HCP - High Condensing Pressure : condensing pressure (transducer BHP) beyond
normal values, but within safety limits
Set HP> 28barg (406psig) delay 3 minutes / Reset HP< 25barg (363psig)
NOTE: with dryer ON, but without compressed air pressure, the drainer failure notice
may
appear.
