23.1.4
E0L2, Pressure switch alarm, suction 2
Terminals
WARNING: THESE TERMINALS FREE VOLTAGE CONNECTION
Set iF07 or iF08 as low pressure switch 2 input: 44-45, high pressure switch input:
[45-46].
Parameters
iP10: Low pressure switch polarity: It establishes if the input is activated by giving (iP10=cL)
or by removing (iP10=oP) main voltage to the terminals.
iP09: High pressure switch polarity: It establishes if the input is by giving (iP09=cL) or by
removing (iP09=oP) main voltage to the terminals.
Actions
Low pressure: every time the inputs are activated all the compressors are switched off. The
instrument restart the standard operating mode when the input is disabled. If there are PEn
activation in the PEi time, only manual resetting is allowed, by pressing the DOWN key for 3s or
by turning off and on the instrument.
High pressure: every time the inputs are activated all the compressors are switched off and fans
are switched on. The instrument restart the standard operating mode when the input is disabled.
If there are PnF activation in the PiF time, only manual resetting is allowed, by pressing the DOWN
key for 3s or by turning off and on the instrument.
23.1.5
EA1÷EA6: Compressors and fans safeties alarm.
Terminals
WARNING: THESE TERMINALS REQUIRE A FREE OF VOLTAGE CONNECTION.
The terminals (from 13 TO 18) really used depends on the number of loads. The protections
regarding the compressors and fans are connected to these inputs. If one of these protections is
enabling (E.I. for lack of oil or overheating, etc,) the corresponding load is turn off.
Parameters
iP01, iP02, iP03, iP04, iP05, iP06:
establish if the input is activated by closing (cL) or by opening
(=oP) the terminals.
Actions
Every time one input is activated the corresponding output is turned off.
Recovery
Recovery depends on
ALMr
parameter:
With
ALMr
=
no
The instrument restart the standard operating mode when the input is disabled.
With
ALMr
=
yES
manual recover for the alarms of compressors and fans. Push the
DOWN
key
for 3s.
23.1.6
P1, P2; P3,P4: probe failure alarm
It is generated by failure in the probe P1, P2 , P3 or P4.
In case of
P1
fault, number of steps engaged depends on the
SPr
parameter
In case of
P2
fault, number of fans engaged depends on the FPr parameter
If the P3 or P4 probes are used for dynamic set point
The function is disabled and only the standard set point is used.
Recovery
Automatic as soon as probe restarts working.
