UdiMatic
(A) The flush time:
Defines the duration of the flushing time per station. The following options are selectable:
5-20 sec in steps of 1 sec
20-55 sec in steps of 5 sec
1-6 min in steps of 0.5 min
The DP setting:
As standard, the Filtron is supplied with an external electronic pressure difference switch. The DP setting
is determined on the external DP sensor, which is set as standard to 0.5 bar. The flush request signal is
indicated in the form of a closed dry contact on the relevant input terminals.
The pressure difference of the external DP sensor may be set using the
screw on the side. One whole turn of 360° adjusts the pressure difference
by 0.1 bar.
Turn anticlockwise to reduce the switching pressure.
Turn clockwise to increase the switching pressure.
(B) The Flush Mode:
The Flush Mode determines how the flush cycle is activated. The
selectable options are:
●
OFF
- no flushing will take place
●
By time
– In this case the flushing cycles will be repeated in a selected interval or will be triggered by
the DP signal depending on what happens first. No matter how was the flushing cycle started the
interval to the next cycle will start to be measured again after each ending of a flushing sequence. The
selectable intervals are the following: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 minutes 2, 3, 4, 5, 6,
8, 12, 18, 24, 72, 120 hours
●
dp
– flushing will be triggered by DP only.
Note:
When the keys ‘+’ and ‘-’ are pressed at the same time, in the field ‘Flush Mode’ the remaining time
until the next cycle is shown in alternating hours and minutes.
(C D E) Accumulations:
The unit independently accumulates and displays the number of flush cycles that are initiated by DP, on
time or manually.
For each of the accumulation fields, the ‘+’ or ‘-’ keys can be used to clear the accumulated value.
The configuration process:
Start the configuration process by holding the ENTER key pressed in for at least 3 seconds. The unit
detects how many plug-in boards (each with two outputs) are in use in the specific case.
How the outputs are assigned depends on the definitions that are set during the configuration process
described below. The following rules apply:
1. Backflush valves will be allocated starting from output 1 and up.
2. The last backflush valve can be canceled and then its allocated output will be left unused.
3. Alarm output, Delay-Valve and Main-Valve when defined, will be allocated in this order, right after the
last backflush valve (whether in use or not).
