Activating the timer namely deletes all causes for stop: If the pump
has previously been manually stopped, for example in
‘Manual’
operating mode at 12 l / h, then it suddenly pumps at 12 l/h when
the timer is activated, which cannot be seen from the timer pro‐
gram.
n If a contact at
‘Config I/O 1’
cannot start the program, then it may
be due to the fact that the contact is not defined as a “Timer input”
(in the
‘Menu / Information
è
Settings
è
Inputs/Outputs
è
...’
menu).
In the same way,
‘Config I/O 2’
(instruction 08) would have to be
defined here as a “Timer output”.
12.4.5 Timer information
There is an option to feed the signals of up to 3 external potential-free con‐
tacts as inputs to the pump via the “Config I/O” connector or issue up to 3
contact signals as outputs (total of inputs + outputs = 3).
Pin assignment - see chapter entitled "Installation, electrical” - "Description
of the connectors".
The function of the pins must be assigned under
‘Settings
è
Config I/Os’
.
The timer software now generates the state of the pump which the pump
would have precisely had at this time if it had not been disconnected from
the mains voltage.
This relates to linked or non-delayed actions.
The timer settings are saved and become effective again when
‘inactive’
switches to
‘active’
.
The operating mode settings are saved and become effective again when
‘active’
is switched to
‘inactive’
.
The pump stores your programming for up to 20 years.
(The calibration and timer data are maintained for up to 100 years).
The time is retained without mains voltage for approx. 2 years.
12.4.6 Typical pitfalls Timer functional faults
Problem Possible cause of fault Remedy
The pump starts pumping unexpect‐
edly.
The timer deletes every “Manual” stop
when activated
- see “Timer behaviour on start”
Enter an
‘Init’
instruction with
‘Halt’
action.
The timer does not react to a con‐
tact signal at the corresponding pin
of the "Config I/O” terminal.
Config I/O was not configured as
“Config I/O” - “Input” in the
‘Menu / Information

Configure Config I/O as “Config I/O” -
