Installing Melter Outputs
The melter is equipped with three user‐configurable 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 pump is on
A fault has occurred
The hot melt level is low
The service LED is on
A potential fault is detected
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 an output to the melter
See Figure 3‐10.
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.
2. Connect each pair of output wires to the appropriate terminals
(1 through 7) on connector P/N 277908. The connector is provided in the
installation kit. Table 3‐9 lists the terminal numbers that correspond to
each output.
NOTE: Terminal number 7 on connector P/N 277908 is reserved for
input number four.Connector P/N 277908 is physically keyed to prevent it
from being used as connector P/N 277909, which has terminals
numbered 8 through 14.
3. Plug connector P/N 277908 into the top receptacle on terminal TB2,
which is located on the main board.
