Unused log entries in the change history log are

indicated by “P‐_” in the right display.

To view how many heater hours have elapsed

since a specific change (displayed) was made,

simultaneously press both of the right‐display

scroll keys.

Setting Up Inputs/Outputs

DuraBlue II adhesive melters are equipped with four standard inputs. Each

input is customer‐wired to the melter and then set up to provide one of the

following control options:

 Place the melter into the standby mode

 Turn the heaters on and off

 Enable or disable a specific hose or applicator

 Enable the motor

The input contacts use a constant 10 to 30 VDC signal voltage. The inputs

are not polarity sensitive.

WARNING! The operator can override the melter inputs by using the control

panel function keys. Ensure that the control logic for any external device that

sends an input signal to the melter is programmed to prevent the creation of

an unsafe condition in the event that the operator overrides an external input

to the melter.

The melter is also 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 motor is enabled

 A fault has occurred

 The hot melt level is low (only if the optional level switch is installed)

 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.

Wire Inputs/Outputs to the Melter

See Figure 3‐6.

1. Route a 2‐, 4, 6, or 8‐conductor signal cable from the control equipment

to the melter and through the PG‐16 penetration on side of the base. 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 input and output wires to the appropriate terminals

on terminal block XI. Refer to Table 3‐6 for the terminal numbers that

correspond to each input.

Set Up Inputs/Outputs

Set up the parameter control option for each input and output that you

connected to the melter. Table 3‐6 lists the available control options. Refer to

Setting Up the Melter earlier in this section for information about how to

select operating parameters and edit parameter control options.

With the exception of the motor

enable/disable control option (Table 3‐6,

Input/Output Data), All inputs are

transition‐based.

Input Setup in Appendix B

The input capacity of the melter may be

increased from four inputs to a total of

ten inputs by adding an optional I/O

expansion card that is available from

Nordson Corporation.

Section 7, Parts

The output capacity of the melter may

be increased from three outputs to

seven outputs by adding an optional I/O

expansion card that is available from

Nordson Corporation.
