Installing Melter Outputs
The AltaBlue melter is equipped with the optional input/output (I/O)
expansion card, which allows four digital outputs. Outputs are used to
communicate with user‐supplied production equipment or control hardware,
such as a programmable logic controller.
Each output is customer‐wired and then set up in the melter's firmware to
provide one of the following outputs:
The melter is ready
The melter is ready and the motor is on
A fault has occurred
The hot melt level is low
The service LED is on
All outputs contacts are rated at 240 VAC 2 A or 30 VDC 2 A. All contacts are
normally open when the melter is turned off.
To connect a digital output to the melter
1. Route a 2‐, 4, or 6‐conductor signal cable from the control equipment to
the melter, through the PG‐16 penetration on the floor of the electrical
compartment. Use rigid or flexible conduit or a suitable strain relief to
protect the cable from the sharp edge of the conduit penetration.
NOTE: Use a signal cable suitable for NEC class1 remote control and
signaling circuits. To reduce the possibility of electrical shorting, route the
cable so that it does not touch nearby circuit boards.
