2.5.4 “CLICK & ROTATE” SWITCH
LOCKING PROCEDURE:
If the LOC parameter is set to ON (in the
configuration 2 menu), the switch is then
automatically locked after 30 seconds if inactive.
To temporarily unlock the switch, depress the
knob for 5 seconds.
If the button is locked and depressed, then a
“LOC” message will be displayed.
2.5.5 ALARM DESCRIPTIONS:
Alarms and faults only show in the standby
Display, either in a fixed or blinking manner with
the temperature value, as outlined below:
Open thermocouple fault:
• Continuous display of this
fault in the standby display.
Reversed thermocouple fault:
• Continuous display of this
fault in the standby display.
Disconnected heating element fault:
• This fault displays alternately
with temperature. An open
heater is automatically
detected by current
measurement. If the measured
current is 0 and if the
percentage of power is greater
than 0, then this is detected as
a load (heater) fault.
Shorted TRIAC fault:
• This fault displays alternately
with temperature. A shorted
TRIAC is automatically
detected if the measured
current differs from 0 and if
the percentage of power =0.
Heating element load resistance fault:
• This fault displays alternately with
temperature. Automatic detection
of load nominal power variation.
after a 120 second stabilization
period of the temperature
control (tempe/- 3 °F / °C
of setpoint), the system keeps
the nominal power in memory
and activates an alarm if there
is a variation of at least –20% with
respect to this nominal power.
Temperature high alarm:
• This fault displays alternately
with temperature. It displays
when temperature is higher
than the se parameter
High alarm value, adjustable in
configuration 1.
Temperature low alarm:
• This fault displays alternately
with temperature. It displays
when temperature is less than
the setpoint parameters Low
alarm value, adjustable in
configuration 1.
