Refer to Section 2-10 for wiring an event input.
The Event input accepts a digital type signal.
types of signal :
relay
or switch contacts,
open collector pull low and
TTL logic level, can be
used to switch the event input.

One of ten functions can be chosen by using
( EIFN ) contained in
setup menu.
One of ten functions can be chosen by using

NONE : Event input has 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.
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.
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, the SP2, PB2, TI2 and TD2 will replace SP1, PB1, TI1 and
TD1 for control.

RS.A1: Reset Alarm 1 as the event input is activated. However, if alarm 1
condition is still existent, the alarm 1 will be retriggered again while the event
input is released.

R.A1.2: Reset both Alarm 1 and Alarm 2 as the event input is activated.
However, if the alarm 1 and/or alarm 2 are still existent, the alarm 1 and/or
alarm 2 will be triggered again while the event input is released.
R.A1.2: Reset both Alarm 1 and Alarm 2 as the event input is activated.
However, if the alarm 1 and/or alarm 2 are still existent, the alarm 1 and/or

The RS.A1, RS.A2 and R.A1.2 are to be used for Latching and/or
Latching/Holding alarms.

D.O1: Disable Output 1 as the event input is activated. The output 1 control
variable MV1 is cleared to zero.
D.O1: Disable Output 1 as the event input is activated. The output 1 control
variable MV1 is cleared to zero.
D.O2: Disable Output 2 as the event input is activated. The output 2 control
variable MV2 is cleared to zero.
D.O2: Disable Output 2 as the event input is activated. The output 2 control
variable MV2 is cleared to zero.
D.O1.2: Disable both Output 1 and Output 2 by clearing MV1 and MV2 values
as soon as the event input is activated.
D.O1.2: Disable both Output 1 and Output 2 by clearing MV1 and MV2 values
as soon as the event input is activated.
When either D.O1, D.O2 or D.O1.2 is selected for EIFN, the output 1 and/or
output 2 will revert to their normal conditions as soon as the event input is
released.
