6.4 - 8 Electrical connection of the error message outputs and the signal inputs (Figure 2 of
appendix)
6.4 Error message outputs
Terminal 1/2 = non-floating alarm output for collective fault.
Caution: a voltage of 230 V/AC is present in the event of an alarm
(This output is fused with a 1 A T microfuse).
Terminal 3/4 = collective fault closed so that it is floating in the event of an
alarm (terminals 1 /2 and 3/4 are active, even in the event of an overflow alarm).
Terminal 5/6 = overflow alarm closed so that it is floating in the event of an
alarm
6.5 Input for float switch for protection against dry running
Terminal 10 /11 = protection against dry running
Polarity of the terminals: 10 = positive and 11 = negative
If a float switch is connected to terminal 10-11, it is possible to prevent the cutter or impeller from emerging
from the medium. Caution: Protection against dry running is only active in automatic mode.
The relevant regulations must be observed for use in areas with a potentially explosive atmosphere.
This input can optionally also be used to lock the system if a special program has been agreed.
6.6 Examples of connections for operating the switchgear with float switches
The display indicates which switch is closed. NO contacts must always be used.
“Float Switches” must be selected in the menu under “Level Control”. The input for the overflow alarm
(terminal 16/17) is always active.
The relevant regulations must be observed for use in areas with a potentially explosive atmosphere.
