Standby Delta
Description:
The number of degrees by which all heated components will be
decreased when the applicator is placed into the standby mode.
Value:
5 _C to 190 _C (10 _F to 350 _F)
Resolution:
1 _C
1 _F
Default Value:
50 _C (100 _F)
Format:
—
Use:
A standby delta 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 of time without charring. Refer to Section 4, Operation, Using
Melter Function Keys.
NOTE: The standby delta does not affect the under temperature delta
(parameter 22).
24
Automatic Standby Timeout
Description:
The amount of time that must elapse after the last signal (applicator
driver) is sent to input 1 before the melter will enter the standby mode.
The automatic standby timeout feature saves energy by allowing the
melter to automatically go into the standby mode if the melter detects that
the applicators are no longer firing.
Value:
0 to 1440 minutes (24 hours)
Resolution:
1 minute
Default Value:
0 (disabled)
Format:
—
Use:
1. Change parameter 23 if required.
2. Set the control option for parameter 30 (input 1) to option 10
(automatic standby)
NOTE: Only enable parameter 24 when a 24 VDC signal voltage is
connected to input 1. If there is no voltage on the input contacts when the
melter is ready, the melter will enter the standby mode after the automatic
standby time.
25
Automatic Heaters Off Time
Description:
The amount of time that must elapse after the automatic standby time
elapses (parameter 24) before the heaters turn off.
Value:
0 to 1440 minutes (24 hours)
Resolution:
1 minute
Default Value:
0 (disabled)
Format:

Use:
Set parameter 24 (automatic standby timeout) to the desired value before
