VEGA VEGASON 71 - 2 … 75 - 2 - Manual (Page 34)

Measurement, Relay output
34 71 - 2 … 75 - 2
Note
-
The relay output included in the pump function
must be coordinated to one channel.
- The switch points 1 (on) must be always above
the switching commands 2 (off) (function B).
- When adding or cancelling a relay output of the
pump function, first all relays and therefore all
pumps de-energize and are switched on again
after 10 secs. with new priority.
Before a manipulation of this type, the impact
should be checked.
Indication of the running period
(maintenance info)
The switching on period of the individual relay
outputs, i.e. the running period of the respective
pump is determined by a software operating hour
counter. This period can be indicated on the display
in the mode range under various mode numbers
(see table below).
The time unit corresponds to 10 1 h.
Programming example for relay output 1 … 3 ....... - mode2
- two-point level switch with pump function switch
in function B
- time interval 1,5 days
Coordination ............................................................. as described on page 31, but also for mode 0 - 48
and 0 - 53
Mode relay output 1 .......................... • select mode 0 - 44 in MODEFIELD
• program figure 2 in PARAMETER FIELD
• then store with STO-button
relay output 2 .......................... • as above, however mode 0 - 49
relay output 3 .......................... • as above, however mode 0 - 54
Switching command 1 and 2 for relay output 1 … 3 as described on page 32 (diagram), however for all
relay outputs with adapted % or m-values.
Time interval ............................................................. • select mode 0 - 63 in MODEFIELD
• program e.g. 2160 min. (1,5 days) in
PARAMETER FIELD
• then store with STO-button
Indication of running period for relay output 1 .......... • select e.g. mode 0 - 47 in MODEFIELD on
display 2 to switch on time of relay output 1 is
indicated, i.e. the running period of pump 1
(example indication 12 ^ 120 hours).
Same procedure for all relay outputs, with
associated mode, numbers see above.
