4. CONFIGURATION
4.12.1. LOW.ON - Alarm due to insufficient current draw
Acronym Scrolling message Submenu Attributes
LOW.ON LOW LOAD CURR THRESH ON TIME AL.HB R W
The parameter shows and sets the current draw value below which the Heater Break alarm trips when the control output
is ON.
If the draw is too low it is assumed that the heating element is broken. The signal may also be caused by a power failure
on the heating element supply line.
Unit of measurement: A
Options: 0.0...999.9
4.12.2. HIG.ON - Alarm due to excessive current draw
Acronym Scrolling message Submenu Attributes
HIG.ON HIGH LOAD CURR THRESH ON TIME AL.HB R W
The parameter shows and sets the current draw value above which the Heater Break alarm trips when the control output
is ON.
If the draw is too high it is assumed that the heating element or its supply line is in short circuit.
Unit of measurement: A
Options: 0.0...999.9
4.12.3. HI.OFF - Alarm due to excessive current draw
Acronym Scrolling message Submenu Attributes
HI.OFF HIGH LOAD CURR THRESH OFF TIME AL.HB R W
The parameter shows and sets the current draw value above which the Heater Break alarm trips when the control output
is OFF.
If the draw is too high it is assumed that the heating element or its supply line (eg a module SSR) is in short circuit.
Unit of measurement: A
Options: 0.0...999.9
4.12.4. TIME - HB alarm trip delay
Acronym Scrolling message Submenu Attributes
TIME WAITING TIME FOR ALHB TRIP AL.HB R W
The parameter shows and sets the minimum time in which the overrun defined by LOW.ON, HIG.ON and HI.OFF must
persist before the HB alarm trips.
This parameter prevents false alarms caused by momentary positive or negative peaks in current draw.
If the value is set to “0” the alarm is immediate.
Unit of measurement: Seconds
Options: 0...999
