Details - Setpoints
MESSAGE NO: S1-06 APPLIES TO: Selected Heater
DEFAULT VALUE: off VALUE RANGE: -50 to 500 °C, off
-58 to 932 °F, off
DISPLAY MODE: All RESTRICTIONS: None
This function sets the High Temperature Alarm setpoint. It must be greater than
the Heater Setpoint. To disable this alarm set the value to “off”. When the Heater
Control Temperature is greater than or equal to this setpoint, the High Temperature
Alarm is activated and a “HIGH TEMPERATURE ALARM” message is added to
the System Status messages. The alarm deactivates when the temperature falls
below this alarm setpoint.
MESSAGE NO: S1-07 APPLIES TO: Selected Heater
DEFAULT VALUE: off VALUE RANGE: 0.5 to 100.0 A, off
DISPLAY MODE: All RESTRICTIONS: Single-Phase Modules
This function sets the Low Current Alarm setpoint. It must be less than the High
Current Alarm setpoint. To disable this alarm set the value to “off”. When the
Heater Current is less than or equal to this setpoint, the Low Current Alarm is
activated and a “LOW CURRENT ALARM” message is added to the System
Status messages. The alarm deactivates when the Heater Current rises above this
alarm setpoint. The value range is in 0.5 A increments. The maximum value for
internal switching Control Modules is 30 A.
Note: This setpoint is based on the heater at 100% power. If Proportional Control
or Power Limit is enabled, all current measurements will be converted to 100%
power, based on a constant resistive load, before being compared to the alarm
setpoint.
MESSAGE NO: S1-08 APPLIES TO: Selected Heater
DEFAULT VALUE: off VALUE RANGE: 0.5 to 100.0 A, off
DISPLAY MODE: All RESTRICTIONS: Three-Phase Modules
This function sets the phase “A” Low Current Alarm setpoint. It must be less than
the phase “A” High Current Alarm setpoint. To disable this alarm set the value to
“off”. When the Heater Current-A is less than or equal to this setpoint, the Low
Current-A Alarm is activated and a “LOW CURRENT-A ALARM” message is
added to the System Status messages. The alarm deactivates when the Heater
Current-A rises above this alarm setpoint. The value range is in 0.5 A increments.
Note: This setpoint is based on the heater at 100% power. If Proportional Control
or Power Limit is enabled, all current measurements will be converted to 100%
power, based on a constant resistive load, before being compared to the alarm
setpoint.
MESSAGE NO: S1-09 APPLIES TO: Selected Heater
DEFAULT VALUE: off VALUE RANGE: 0.5 to 100.0 A, off
DISPLAY MODE: All RESTRICTIONS: Three-Phase Modules
This function sets the phase “B” Low Current Alarm setpoint. It must be less than
the phase “B” High Current Alarm setpoint. To disable this alarm set the value to
“off”. When the Heater Current-B is less than or equal to this setpoint, the Low
Current-B Alarm is activated and a “LOW CURRENT-B ALARM” message is
added to the System Status messages. The alarm deactivates when the Heater
Current-B rises above this alarm setpoint. The value range is in 0.5 A increments.
Note: This setpoint is based on the heater at 100% power. If Proportional Control
or Power Limit is enabled, all current measurements will be converted to 100%
power, based on a constant resistive load, before being compared to the alarm
setpoint.
