INDICATIONS INDICATIONS
The instrument shows the OVERRANGE
condition with the following indication on the
upper display:
The instrument shows the UNDERRANGE
condition with the following indication on the
upper display:
The sensor leads break can be signalled as:
- for TC input : OVERRANGE or
UNDERRANGE selected by a
solder jumper (see Fig. 12).
- 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).
NOTE NOTE: When: NOTE NOTE NOTE
- The instrument is set for one output only and an
OVERRANGE is detected, the OUT 1 turns
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 turn 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).
- The instrument is set for heating/cooling action
and an UNDERRANGE is detected, OUT 1
turns ON and OUT 2 turns OFF.
ERRORS ERRORS ERRORS ERRORS ERRORS
Diagnostics are made at instrument switch-on
and during normal mode of operation.
If a fault condition (error) is detected, the lower
display will show the message "Er" while the
upper display shows the relative error code.
