– Relay control lamp
– The yellow relay control lamp reacts depending on the set
mode (A/B)
– The relay control lamp generally indicates the activated (ener-
gized) condition of the relay
– A dark relay control lamp means that the relay is deenergised
(transistor blocks)
Laterally on top (covered when mounted) there is a DIL switch block
with six switches. The individual switches are assigned as follows:
•
1 - A/B mode
– A - Max. detection or overflow protection
– B - Min. detection or dry run detection
•
2 - Switch off delay (za)
•
3 - Switch on delay (ze)
•
4 - Switching delay 2 s
•
5 - Switching delay 6 s
•
6 - Switching delay 12 s
With switch 1 you can adjust the mode (A - overfill protection or B -
dry run protection).
With switches 2 and 3 you can set switch off and/or switch on delays
independent of each other.
The delay refers to the switching function of the relay.
In the example (see previous illustration), mode A (max. detection of
overfill protection) is selected (switch 1). The switch off delay is acti-
vated (switch 2) and the switching delay is set to 8 seconds (switch 4,
5 and 6).
With switches 4, 5 and 6 you can adjust the switching delay. The times
of the activated time switches accumulate. If the switch on (ze) and
switch off delay (za) are switched on together, the set time applies to
both delay modes.
Hence the relay deenergises with 8 seconds delay time when the
switching point is reached.
Information:
Keep in mind that the switching delay of the sensor and signal condi-
tioning instrument accumulate.
