Hold and external control inputs
6.8.1
Hold function, freezing the outputs
In order to avoid unintentional changes to the
current outputs or controller contact positions
during configuration or calibration, the
present status can be “frozen” or a set
current value can be specified.
Warning:
Ongoing Chemoclean cleaning
cycles are carried out even if the
hold function is activated.
See:
• Chapter 6.7, short cut to relays menu,
hold on / off
• Chapter 7.2, current output menu, type of
hold: set current value / last measurement
• Chapter 7.5, calibration menu,
hold with calibration: yes / no
• Chapter 7.6, Chemoclean menu,
Hold with Chemoclean: on / off
6.8.2
External control inputs
Binary input 1: terminals 81 / 82
Binary input 2: terminals 83 / 84
Note:
The binary inputs are only available
on instruments with the additional
FCXI module and require an
additional external power supply
(nominal 12 V).
External Hold input:
If no cleaning or assembly functions have
been set, both of the binary inputs act as
external hold inputs.
Warning:
Ongoing Chemoclean cleaning
cycles are carried out despite an
external hold signal.
External control in the case of cleaning without retractable assembly
(for adjustment see chp. 7.1.3, »relays allocation«)
