Part Description

313997 HFR Operation

313998 HFR Repair-Parts

2 3A1149D

Overview

This Discrete Gateway Module (DGM) allows the user to control an HFR through an external control device such as a PLC. The DGM will operate in conjunction with the existing Advanced Display Module (ADM) such that both devices can be used to control the machine. Each HFR can be controlled using up to two DGM’s which will be referred to as the primary and secondary DGM’s.

The primary DGM allows the user to monitor and control general machine functions. This includes the following capabilities:

• Dispensing

• Operating mode selection

• Shot selection

• Fault code monitoring

• Fault acknowledgment

• Pump parking

• Monitoring working pressures of each pump

• Monitoring the combined flow or B (Blue) pump pressure while dispensing

• System Stop button

• Changing the combined flow or B (Blue) pump pressure in operator mode

Automation Presence

The primary DGM includes a heartbeat monitor. This serves as a verification that the PLC and DGM are communicating. In the event that the PLC becomes unresponsive, the DGM will terminate any active dispenses and set the machine to disabled mode.

The secondary DGM is used for monitoring and controlling the temperature conditioning components. These features include:

• Monitoring which conditioning zones are enabled

• Monitoring temperatures of enabled zones

• Turning on or off the enabled zones

• Changing temperature setpoints of enabled zones

NOTE: Changing temperature setpoints is only available on machines with 2nd generation ADMs. 2nd generation ADMs are distinguishable by having only 2 cable connections on the bottom of the ADM. 1st generation ADMs have 4 cable connections.

DGM Presence

The DGM will broadcast a heartbeat to the HFR every 5 seconds. In the event that the DGM fails to broadcast a heartbeat after 10 seconds, the system will go into disabled mode.

The system can be taken out of disabled mode after acknowledging the alarm on the ADM.

Module Requirements

Each DGM requires a 9-30 VDC NEC Class 2 power supply. This is supplied to the DGM through pins 27, 51, 68, 69 on the D-Sub connection. Ground from this supply should only be connected to pin 70 of the D-Sub connection.

I/O Setup

NOTE: Each DGM is set as the primary or secondary

DGM by setting the rotary switch (AG) position. See Setup on page 14.

NOTICE

To avoid ground loops and noise immunity issues, do not ground the shield of the D-sub connector cable. The shield is already grounded through the mounting screw on the base of the DGM. If using a breakout board, do not make any connections to the pins with ground symbols.

See the Digital and Analog I/O Overview sections beginning on the following page for I/O setup details. See the

Primary DGM Pin Assignments and Secondary DGM Pin Assignments sections beginning on page 10 for

individual pin assignments.

I/O Setup

DGM Digital Input Overview

The digital inputs function only when power is supplied to pin 51 and there is a ground connection to pin 70. The digital input is rated at 0-30 VDC, and requires an NEC Class 2 power supply connected to pin 51. The DGM provides optical isolation as shown in the following illustration.

• Pins: 52 – 59, 71-78

• Type: Sinking

• Maximum current draw: 3.6 mA
