Changing and Scanning the Basic Values

5. Input function parameters

5.15

If the system cut-out has
been programmed, you can
specify whether the system
should

come

back

on

automatically once the fault has been rectified or have to be restarted manu-
ally.

Define the phases in which
the "external alarm switch"
input is monitored.

"|" Input is monitored

"

-

" Input is not monitored

Press INFO to see the meaning of the abbreviation in plain text.

P

= Production phase

R3 = Rinse during production phase

R1 = Rinse after production phase

M

= Maintenance phase

R2 = Rinse during standby phase

S1 = Standby phase 1

The external alarm switch is not monitored during the stop and standby
phases

Stop

Define the phases in which
the "stop" input should be
active (see programming
step 10.1).

"|" Input is active

"

-

" Input is inactive

Press INFO to see the meaning of the abbreviation in plain text.

P

= Production phase

R3 = Rinse during production phase

R1 = Rinse after production phase

M

= Maintenance phase

R2 = Rinse during standby phase

S1 = Standby phase 1

Stop manual start

If the stop manual start
option is set to "Y" (yes),
the "stop manual start" LCD
comes on when the stop

input is activated. The system must be restarted again by pressing "ON".
If the stop manual start option is set to "N" (no), the "Signal stop " LCD comes
on when the stop input is activated. The system continues its normal
functions as soon as the stop signal at the input is cleared.

Power failure

You can program whether the system should remain
in the "standby stop" phase if a power failure occurs
or commence its normal cycle immediately, com-
mencing in general with a rinse phase.
All inputs are deactivated and no outputs are acti-

vated during the "standby stop" phase. The system must be started manually.

WARNING! If a power failure occurs during the "maintenance" phase, the controller returns to the
"stop maintenance" phase. If a code number has been defined for the maintenance phase, this must
be re-entered before the maintenance phase can be restarted.
