PANELMETER FUNCTIONS
Any input value that can be compared with value for limit switch can be selected for signalling of emergen-
cy condition. Value for limit switch can be selected with shift from required value SP or from value of limit
switch ALSP (x). Select value in menu MODE (x). Set state of output relay (whether it should switch on or
off after exceeding of required value) in menu with command RELE (x).
Limit switch alarm is delayed by hysteresis set with command HYST (x).

rele
(x)
Setup of output relay positing at exceeding of limit switch va-
lues.
OFF
switches off with exceeding the value.
ON
switches
on.
Value of limit
switch
alsp
(x)
Setup of limit switch alarm value.
Required value
sp
Setup of required value. Required value is common for all limit
switches and is important only with setting
MODE
to
SHIFT
.
Mode
mode
(x)
Assigning of limit switch value for evaluation.
STATE
value of
alarm
ALSP
(X) is directlly connected to limit switch
SHIFT
value SP shifted by the value of alarm
ALSP
(X) is con-
nected to limit switch.
Hysteresis
hyst
(x)
Setup of switching hysteresis of output relays.
Output signalling
tral
(x)
Alarm for limit switch can be temporarry TRAl (x) = NO or per-
manent TRAl (x) = YES.
a) Temporary limit switch alarm goes off after elapsing of alarm
conditions.
b) Permanent limit switch alarm is on even after elapsing of
alarm conditions. Alarm can e switched off after elapsing of
alarm conditions with pressing key SET. Permanent alrm is also
switched after power supply failure.
Caution:
1) Limits of limit switches in mode STATE are set in absolute values.
2) Limits of limit switches in mode SHIFT are set as deviations
from required value SP.
