Description of Components
The following items are referenced to the illustration on previous page:
• Item #1 The controller runs on standard 24VDC. The supply voltage, coming from the
24VDC power supply, is connected to this terminal. The input is polarity sensitive.
• Item #2 The operator’s panel connects to this header via a ribbon cable. There are
several types of operator’s panels available. They are interchangeable.
• Item #3 This connector provides customer accessible relay contacts. There are three
pairs of dry contacts which are designed for maximum 240 VAC/1A.
The default functions of the relays are:
Relay 1: Ready Signal
This contact closes once the system is in ready condition (ready condition = all active
temperature zones are within their tolerances and there is no other alarm message
pending). Normally open. A Drum Empty alarm message will not remove the Ready
condition.
Relay 2: Alarm Signal
This contact opens whenever a critical situation arises. A critical situation could be a
defective temperature sensor, an over or under temperature situation, a motor driver
fault, etc. Normally closed.
Relay 3: Drum Empty Signal
This contact closes when the adhesive level in the drum drops below a certain level. It
can be used to indicate this situation via an external light or an audible alarm. Normally
open.
Note: Depending on the controller’s settings, one or more of the relay outputs may be re-
programmed for different purposes. In this case, refer to corresponding set-up
instructions.
• Item #4 This connector is used for a module-to-module connection. It provides the
power-on signal to the power board through the TEMP board. In the case of a critical
alarm, this 24 VDC signal will drop, cutting off the heater power on the power boards.
This signal may also control the main contactor.
• Item #5 This connector accepts external signals that can be used to control the ASU.
The inputs require 24VDC signals. Although the internal 24VDC can be used to
provide voltage for the inputs, it is recommended to use external 24VDC. For this
purpose the common of the signal inputs is available on terminal IN-C. and is isolated
from the internal 24VDC.
All inputs are not polarity sensitive. That means the common (IN-C.) can either be
positive or negative.
