OLH
Output high limit (in % of the output).
This parameter is present if PB
parameter is different from 0 only.
Range:
- From 0.0 to 100.0 when device is
configured with one control output.
- From -100.0 to 100.0 when device is
configured with two control outputs (LHS
only).
tOL
Time duration of the output power
limiter.
The tOL is a programmable time in
which the output level is limited to OLH
value.
The count of this time starts at
instrument switching on if the measured
variable is less than the threshold value
programmed (P10 parameter).
This parameter is present if PB
parameter is different from 0 only.
Range: from 1 minute to 100 minutes.
Above this limit, the upper display shows
"InF" and the limiter will be ever enabled
independently from P10 parameter
value.
Note: The tOL can be modified but the

new value will become operative only at

The instrument shows the OVERRANGE and
UNDERRANGE conditions with the following
indications:
Overrange
The sensor leads break can be signalled as:
- for TC input : OVERRANGE or
UNDERRANGE selected by a
solder jumper (see chapter 3)
- for RTD input : OVERRANGE
Sensor leads short circuit detection:
On RTD input, a special test is provided to signal
OVERRANGE when input resistance is less than
15 ohm (Short circuit sensor detection).

OFF (if reverse action) or ON (if direct action).
- The instrument is set for heating/cooling action
and an OVERRANGE is detected, OUT 1 turns
OFF and OUT 2 turns ON.
- The instrument is set for one output only and an
UNDERRANGE is detected, the OUT 1 turns
ON (if reverse action) or OFF (if direct action).
