4.3.1
Low-level and empty status signalling of the suction kit
Attention
The low-level and empty status signals are defined in the factory as normally open
contacts (NOC).
If the signal input Ext. Stop of the JUDO UNIDOS digital dosing pump system is used,
both switching contacts on the suction kit must be defined as normally closed contacts
(NCC) by rotating as must the signal input under mode 1 (see Chap. 5.2.5)!
Fig. 6: Low-level and empty status signalling
To check and if necessary to correct:
The switch contacts must be fitted on the suction kit according to their switch function (see switch
symbol on the switch contacts).
The suction kit must be inserted up to the bottom of the dosing tank.
