Chapter 4 Full Function Programming
4–1 Event Input
Refer to section 2-10 for wiring an event input.
The event input accepts a digital type signal. Dry contacts or open collector pull low can
be used to switch the event input.
One of ten functions can be chosen by using (EIFN) in the setup menu.
NONE:
Event input no function
If chosen, the event input function is disabled. The controller will use PB1, TI1, and TD1
for PID control and SP1 (or other values determined by SPMD) for the set point.
SP2:
If chosen, the SP2 will replace the role of SP1 for control.
PID2:
If chosen, the second PID set PB2, TI2, and TD2 will be used to replace PB1, TI1,
and TD1 for control.
SP.P2:
If chosen, SP2, PB2, TI2, and TD2 will replace SP1, PB1, TI1, and TD1 for
control.
NOTE:
If the second PID set is chosen during auto-tuning and/or self-tuning procedures,
the new PID values will be stored in PB2, TI2, and TD2.
RS.A1:
Resets alarm 1 as the event input is activated. However, if the alarm 1 condition
is still existent, alarm 1 will be retriggered when the event input is released.
RS.A2:
Resets alarm 2 as the event input is activated. However, if the alarm 2 condition
is still existent, alarm 2 will be retriggered when the event input is released.
R.A1.2:
Resets both alarm 1 and alarm 2 as the event input is activated. However, if
alarm 1 and/or alarm 2 are still existent, alarm 1 and/or alarm 2 will be triggered again
when the event input is released.
RS.A1, RS.A2, and R.A1.2 are particularly suitable to be used for latching and/or
latching/holding alarms.
D.O1
: Disables output 1 as the event input is activated.
D.O2:
Disables output 2 as the event input is activated.
D.O1.2:
Disables both output 1 and output 2.
When any of D.O1, D.O2, or D.O1.2 are selected for EIFN, output 1 and/or output 2 will
revert to their normal conditions as soon as the event input is released.
LOCK:
All parameters are locked to prevent them from being changed. See section 4-13
for more details.
