Pot Fill - External Low Level Detection
Pot Fill is used when the hot melt control is being used to heat the hot melt adhesive and remotely fill a pot. Using the
Pot Fill mode, the hot melt control can precisely monitor the pot level and fill the pot on demand from the low level
sensor mounted in the pot.
For setup details, refer to
Section 5
.
Hopper Feeder - Internal Low Level Detection
The Hopper Feeder option is used to refill the hot melt control’s tank with fresh adhesive when the tank level drops
below the set level sensor. This eliminates the need for the operator to manually open the tank lid and add adhesive
to the tank.
For setup details, refer to
Section 5
.
Beacon Alarm
The Beacon / Alarm output connector is provided as a ded24VDC @ 0.5A output for a visual or audio alarm.
This can be set up to alert the operator of one of 4 fault conditions (see Section 5 – Setup for description).
The installer can connect the “+” lead of the alarm to Beacon 1 (pin 3) and the “-” lead to GND (pin 1) of J30 on the
CPU board. When the Beacon / Alarm screen is set up for an alarm condition, the +24VDC output will enable the
alarm device to signal that the condition on the control has been met (eg. Low Level).
External Input
The External Input can accept 230VAC, 24VAC or +24VDC to reset the Setback Timeout when the control is in Auto.
Setback. This is used in special applications and the programmable inputs should be used for this feature (see
Automatic Setback above). The pin out for this connector on the CPU board is critical (see Section 5 – Setup for this
connector location).
