Compressor Regulation Type
RC: Regulation Control
L:
0 or 100%, Load/Unload control.
For single pressure switch type
regulation.
AR:
0 to 100% analogue output regulation
with Load/Unload control.
AC: Analogue Output Control
3S:
0/50/100% regulation control.
For duel pressure switch type
regulation of 3-stepping reciprocating
compressors.
5S
: 0/25/50/75/100% regulation control.
For quad pressure switch type
regulation of 5-stepping reciprocating
compressors.
V:
Poppet value regulation control.
VC: Valve Control
AD
Comp. Number (Network Address)
The compressor network address number
must be unique; if two compressors are
assigned the same network address number
system management unit control will be
disrupted.

‘i-PCB’ Alarm Input 0V/+V
The ‘i-PCB’ Alarm input configuration.
+V=!
An Alarm condition is
generated if the ‘i-PCB’ Alarm input
detects a voltage between 12-
250Vac/dc (
default
).
0V=!
An Alarm condition is
generated if the ‘i-PCB’ Alarm input
detects no voltage.
Set to default ‘

Level
Fan temperature control option: fan output will
de-activate when temperature T01 falls below
the ‘FL’ level.
FH
Fan High Temperature Level
Fan temperature control option: fan output will
activate when temperature T01 exceeds the
‘FH’ level.
Auxiliary Relay Output Functions
FR
Fan Minimum Run Time
Fan temperature control option: once activated
the Fan output will not de-activate untill ‘FR’
time has elapsed, regardless of temperature
levels. This function is intended to limit Fan
motor starts-per-hour.
