*ATM
NON;
ABS;
REL
Alarm threshold management.
NON: all temperature alarms are inhibited
(the following parameter will be
SB)
.
ABS: the value programmed in
ALM
and
AHA
represent the real alarm thresholds.
REL: the value programmed in
ALR
and
AHR
are alarm differentials reerreed to
1SP
and
1SP+1HY

ALR
-12..0°
Low temperature alarm differential.
With AHR=0 the high temperature is excluded.
AHR
0…12.0°
High temperature alarmdifferential.
With AHR=0 the high temperature is excluded.
*ATD
0…120 min
Delay before alarm temperature warning.
*SB
NO / YES
Stand-by button enabling.
*INP
0mA/4mA
Sensor input selection (see table of input specifications).
*RLO
-19.9…RHI
Maximum range values.
RLO
takes the maximum value measured by the transmitter
(i.e. the value matching 1V, 20mA)
*RHI
RLO..99.9
Maximum range vlue RHI takes the maximum value measured by the transmitter (i.e.
the value matching 1V, 20mA).
*OS1
-12.5..+12.5
Probe T1 offset.
*TLD
1…30min
Delay for minimum temperature (TLO) and maximum temperature (THI) logging.
*SIM
0…100
Display slowdown
*ADR
1…255
Address for PC communication.
