5.5 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 4.
5.6 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 4.
5.7 BEACON ALARM
The Beacon / Alarm output connector is provided as a dedicated
+24VDC @ 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).
5.8 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 4 for this connector
location).
