d.i.F.1 digital input 1 function
0 no function (key not active)
1 reset trip memory
2 reset peak memory
3 reset trip memory + reset peak memory
4 tare reset
5 tare reset + setpoint memory reset
6 tare reset + peak memory reset
7 tare reset + setpoint memory reset + peak memory reset
8 calibration check (only for 6-wires Strain-gauge probes)
9 remote setpoint 1 on (•)
10 remote setpoint 2 on (•)
11 remote setpoint 1+2 on (•)
12 display HOLD function (the display remains "frozen" as long as the key is pressed); the process variable continues
to be sampled and the setpoints function normally
13 HOLD function for sampled input value (the sampled input value and the setpoints remain "frozen" as long as the
digital input is active). With the digital input active, a reset of the setpoint memory de-energizes all energized relays
and resets all alarm memories.
14 FLASH function for sampled input value (see section on setpoint function).
15 probe feed check. Digital input 1 (IN1) used to check probe feed must be polarized (type PNP) (see configuration of
digital inputs). The digital input has to be connected in parallel to the probe feed. Connect faston 4 to -Exc, faston 6
(diF1) to +Exc. If the probe receives no power, the display shows E.br; outputs (out) go to configuration state (rEL).
Note: the input HOLD and FLASH functions are mutually exclusive.
(•) Remote setpoint enabled: REM LED on, tYPr1 and/or tYPr2 must also be enabled in CFG3.
d.i.F.2 digital input 2 function
0 no function (key not active)
1 reset trip memory
2 reset peak memory
3 reset trip memory + reset peak memory
4 tare reset
5 tare reset + setpoint memory reset
6 tare reset + peak memory reset
7 tare reset + setpoint memory reset + peak memory reset
8 calibration check (only for 6-wires Strain-gauge probes)
9 remote setpoint 1 on (•)
10 remote setpoint 2 on (•)
11 remote setpoint 1+2 on (•)
12 display HOLD function (the display remains "frozen" as long as the key is pressed); the process variable continues
to be sampled and the setpoints function normally
13 HOLD function for sampled input value (the sampled input value and the setpoints remain "frozen" as long as the
digital input is active). With the digital input active, a reset of the setpoint memory de-energizes all energized relays
and resets all alarm memories.
14 FLASH function for sampled input value (see section on setpoint function).
15 probe feed check. Digital input 1 (IN1) used to check probe feed must be polarized (type PNP) (see configuration of
digital inputs). The digital input has to be connected in parallel to the probe feed. Connect faston 4 to -Exc, faston 7
(diF1) to +Exc. If the probe receives no power, the display shows E.br; outputs (out) go to configuration state (rEL).
Note: the input HOLD and FLASH functions are mutually exclusive.
(•) Remote setpoint enabled: REM LED on, tYPr1 and/or tYPr2 must also be enabled in CFG3.
out_1 output 1 function (the out1 setpoint value can only be absolute. See section on trip point function).
0 direct absolute (direct function same as having an energized relay for values above set trip point).
1 reverse absolute (reverse function same as having an energized relay for values below set trip point).
6 absolute direct window ( ♣ )
7 absolute reverse window ( ♣ )
+8 to code selected for action disabled at power-on untill the first trip point
(useful in case of inverse trip point due to minimum alarm).
+16 to code selected for trip point with memory.
+32 to code selected for probe interrupt or power failure alarm (In this case, you have to use DIGITAL INPUT 1 or
DIGITAL INPUT 2 configured d.i.F.1 = 15, d.i.F.2 = 15). Relay state depends on parameter rEL. When the probe is
not interrupted, the output functions normally. In case of probe error such as "energizing interrupted," the display
shows message E_br.
+64 to code selected for timed trip point delay (in this case, hysteresis is set in msec. and becomes the delay time in
activation of output compared to time of tripping).
+128 to selected code to not subject absolute alarm setpoints to tare zero.
