Machine-Stop Relay and Beacon Interface
An optional machine stop relay and beacon interface (option D1) is required to indicate a jam condition or glue
inspection fault to the parent machine. Normally open and normally closed contacts are provided at a male connec-
tor mounted to the cord grip base plate. Contact rating is 24VDC or 24VAC at 2A.
When a jam condition is detected, the machine stop relay is energized. The relay is de-energized when the speed of
the parent machine drops below the minimum speed setting (see the level-3 menu screen). The front-panel jam
indicator also illuminates.
A field-wireable mating connector (Figure 13a) is provided to wire the relay contacts to the parent machine stop
circuit. Connections are as follows:
Pins 1 and 2: Normally closed contact
Pins 3 and 4: Normally open contact
DD-1 Pump Power Supply
A source is available to supply power for a DD-1 pump at connector J6 of the power supply board (151xx368). This
supply is 32VDC, fused at 1.6A, with connections as follows:
Pin 1: 0 V
Pin 2: 32VDC
Since the DD-1 pump is configured to accept an AC source and then rectify it to DC, polarity of a DC source is not
relevant.
Bypass Valve Driver
A bypass valve (or dump valve) may be needed to divert excess glue in the glue line away from the applicator to
avoid puddling during startups and quick stops. A 12VDC, 1A driver is available at connector J8 of the interface
board. Connections are as follows:
Pin 1: 12V
Pin 2: Signal
An optional beacon with audible alert can be remotely mounted to
indicate a jam condition. A female connector mounted to the cord-
grip base plate provides the connection point for beacon/alarm
signals. Connections are as follows:
Pin 1: 12VDC
Pin 2: Glue fault (blue) light
Pin 3: Jam (red) light
Pin 4: Audible alarm signal
A pre-wired cable is provided with the beacon.
