Over Temperature Delta
Description:
The number of degrees that the temperature of any component can increase
over its assigned set‐point temperature before an over temperature fault (F3) will
occur.
Value:
5 C (10 F) to 60 C (110 F)
Resolution:

Under Temperature Delta
Description:
The number of degrees that the temperature of any component can decrease
from its set‐point temperature before an under temperature fault (F2) occurs.

Standby Delta
Description:
The number of degrees by which all heated components will be decreased when
the melter is placed into the standby mode.
Value:
25C to 190C (50F to 350F)
Resolution:
1C
1F
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 set‐point 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, 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 guns 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 setting
parameter 25.

Manual Standby Time
Description:
The amount of time that the melter will remain in the standby mode after the
standby key is pressed.
Value:
0 to 180 minutes
Resolution:
1 minute
Default Value:
0
Format:
—
Use:
Set the standby time when you want the operator to be able to place the melter
into the standby mode for a limited period of time (break, lunch, etc.). When
manual standby is enabled (value greater than 0 minutes), the standby LED
blinks.
Set the standby delta (parameter 23) to the desired value before setting
parameter 26.
Note: When a time value equal to or greater than 1 minute is entered, the
standby LED will flash to indicate that the manual standby timer is counting
down.
27
Hose Standby Delta
Description:
The number of degrees by which all heated hoses will be decreased when
the applicator is placed into the standby mode.
Value:
1 C to 190 C (1 F to 350 F)
Resolution:
1 C
1 F
Default Value:
0
Format:
—
Use:
This parameter functions like parameter 23 except when it is set to 0, in
which case it reverts to the setting for parameter 23.
NOTE: The standby delta does not affect the under temperature delta
(parameter 22).
28
Applicator Standby Delta
Description:
The number of degrees by which all heated guns will be decreased when
the applicator is placed into the standby mode.
Value:
1 C to 190 C (1 F to 350 F)
Resolution:
1 C
1 F
Default Value:
0
Format:
—
Use:
This parameter functions like parameter 23 except when it is set to 0, in
which case it reverts to the setting for parameter 23.
NOTE: The standby delta does not affect the under temperature delta
(parameter 22).
