The output function defines what condition causes the output to turn on and off. All digital outputs are
configured as event outputs by default. More than one output can be set for the same function.
Event:
When selected, the output is controlled directly from the corresponding
event on the Overview screen and Program Entry screen. When the event
is selected, the output turns on. When the event is not selected, the output
turns off.
Program Running:
When selected, the output will turn on when a ramp/soak program is active.
The operating condition is defined as a ramp, soak, guaranteed soak or
wait for condition. The output will not be on if the program is in autostart,
since it has not yet started, or when it is placed in hold by an operator.
Program Paused:
When selected, the output will turn on when the program is in hold. When
the program is in any other condition, the output will be off.
Step Change:
When selected, the output will provide a one-shot pulse each time the
program changes steps. This also includes an output pulse each time the
program is manually advanced to the previous or next step while in hold.
When a program is started, the output will pulse when the first
step of the program is started.
Input Alarm:
When selected, the output can be controlled by a loop/monitor input alarm.
The alarm must be configured to control the output. See Section 5.4,
Alarms for information on assigning the alarm to the event output. This
output mode provides a way of controlling devices at specific temperature
or humidity levels for example.
If more than one alarm is assigned to the output, the output
will not operate correctly and may cycle on and off
uncontrollably. Do not assign more than one alarm to an
output.
Chamber Alarm:
When selected, the output will turn on when a critical alarm occurs. The
output will stay on until the alarm is reset. This output mode provides a
remote alarm notification that operates in conjunction with the chamber’s
audible alarm. Note that the alarm condition may still exist with the output
turned off.
Digital Input 1-8
These mode selections are
used to assign the output to one of the digital
inputs. It allows a digital input to turn the output on and off directly. Any of
the eight available inputs can be selected for control of the output.
The digital input must be configured for event output control for
the output to be controlled by the assigned digital input. If the
input is not configured for event output control, the output will
remain off.
