22 Undertemperature Delta
Description:
The number of degrees that the temperature of any component can fall below
its assigned setpoint temperature before an undertemperature fault (F2) occurs.
Value:
5 _C (10 _F) to 60 _C (110 _F)
Resolution:

Default:
25 _C (50_F)

23 Standby Delta (Global)
Description:
The number of degrees that the temperature of all heated components will be
decreased when the melter enters standby mode.
Value:
25_C to 190_C (50_F to 350_F)
Resolution:
1_C
1_F
Default:
50 _C (100_F)
Format:
—
Use:
A Standby delta (= differential value) should be selected that results in a
balance between melter energy savings during periods of inactivity, the amount
of time and energy required to bring the melter back up to setpoint temperature,
and a temperature at which the hot melt can be held in the tank for extended
periods without charring.
NOTE: The Standby delta does not affect the Undertemperature delta
(parameter 22).
24 Automatic Standby
Description:
The amount of time that must elapse after the last signal (gun driver) is re-
ceived by input 1 before the melter enters standby mode. The Automatic
standby feature saves energy by allowing the melter to enter standby mode as
soon as the guns are no longer applying material.
Value:
0 to 1440 minutes (24 hours)
Resolution:
1 minute
Default:
0 (disabled)
Format:

Use:
1. Change parameter 23 if required.
2. Set parameter 30 (input 1) to control option 10 (automatic standby).
NOTE: Only enable parameter 24 when a 24 VDC signal is connected to
input 1. If there is no voltage on the input contacts when the melter is ready, the
melter will enter standby mode when the Automatic standby time has elapsed.
