Alarm menu
To call the menu, select:
"

7.6.8
Set up 1 - Hold
The current outputs can be "frozen" for each menu. This means that the value which you define in
this menu is output. With hold, "Hold" appears in the display. This function can also be activated
externally by means of the hold input (see the "Connecting external inputs" section). The onsite
hold has a higher priority than an external hold.
!
Note!
• If Topcal S is activated as the hold source, hold is active as soon as the assembly goes to the Service
position.
• If a hold is active, no new automatic programs are started. They can be started externally or via
local operation where necessary.
• You can deactivate Topcal S as the hold source
(PARAM > Set up 1 > Hold > CPC off).
• If current output 2 is configured for the controller, it obeys the controller hold (see the last field
in the table).

• Min (2.4mA)
• Max (22 mA)
• Off
Factory setting
Max (22 mA)
Set the error current at which an error message
is active.
Note
Caution!
Current output 0 ... 20mA and
error current = 2.4 mA is critical.
The error current is in the measured current
range if the current range selected is "0 ... 20
mA" and "Min" was selected in the previous
field.
Recommended combinations:
• Current range 0...20 mA and error current
max (22 mA)
• Current range 4...20 mA and error current
min (2.4 mA)
Alarm delay
0 ... 2000 s
Factory setting
0 s
Specify the delay time from when the error
occurs to when the alarm is triggered.
Error/contact assignment
Activation and subsequent entry
• R (alarm relay)
– On
– Off
• I (error current)
– On
– Off
• CC (Chemoclean)
– On
– Off
The function the error triggers can be
individually assigned to each error:
R:
Assignment to alarm relay. An activated
error triggers an alarm.
I:
This error triggers an error current.
CC:
Chemoclean. This error triggers a cleaning.
Dose-time alarm
Activation and subsequent entry
• Function
– On
– Off
• Time
2 ... 9999 s
Factory setting
Function: Off
Time: 2 s
Activate or deactivate the alarm if the dosage
time is overshot.

Enter the maximum dosing time
permitted. An alarm is output once this time
elapses.
