6.22.2 Outputs
Each output group is a single-pole changeover relay element that is rated at
240 volts, 1 amp maximum.
It is comprised of a moving contact (MC) is connected to a normally-closed
(NC) contact when de-energized. When the controller activates output 1 or
2, the normally closed (NC) and moving contact (MC) go to open circuit while
the normally open (NO) and moving contact (MC) go to short circuit.
Optional outputs that may be selected are as follows:
Table 6-8 Quad IO Outputs
Option
Description
Boost
An output is given if the controller is put, either locally or
remotely, into Boost mode.
Cavity Alarm
Output is given if any cavity zone (usually an RTD sensor)
deviates from its set temperature enough to generate a
second stage alarm.
Controller
Alarm
Output is given if any alarm is generated. This mimics the
secondary output alarm / beacon.
Hot Runner
Output is given if any probe (nozzle) or manifold deviates
from its set point enough to generate a second stage
alarm.
Inactive
Output will not be used and remains inactive.
Inj Disable
Output is seen if the system is idle.
Output is cleared once the system has started up and
gone into Run mode.
Output is given if system has an out-of-limits alarm.
No other alarm, for example Fuse or T/C, causes output to
be given.
Inj Disable
Ext
Output mimics Injection Disable in order to provide two
identical outputs.
Pressure
Alarm
Output is given if any pressure sensor gives a pressure
reading that deviates from its setpoint enough to generate
a second stage alarm.
Stopped
Output is given if the controller is automatically put into
Stop mode by any detected alarm condition.
It is not activated if the controller is manually put to Stop
mode by the user.
Temp Dist
Output is given if any Fatal Error occurs, for example Fuse
or T/C.
Warn
A new proposed output which will be given if any zone
deviates from its setpoint enough to generate a first stage
warning.
Water Flow
Output is given if any flow sensor gives a flow reading that
deviates from its nominal setpoint enough to generate a
second stage alarm.
