4.2.2 Status Relay
The controller is equipped with a status relays according to the following
illustration:
The following switching states can be analysed:
The load rating of the status relay is maximum 30 V DC for direct current and max-
imum 125 V AC for alternating current with a maximum of 0.3 A in both cases.
Destruction of the operational transmitting relay and possibly of the controller!
When dimensioning, note the permissible values given above for the load of the
operational transmitting relay.
4.2.3 Coarse and fine Fill Rates
When using the controller for dosing and filling processes, we recommend a cir-
cuit as shown in Figure 4.6. In this circuit the two relays K1/K2 function as fol-
lows:
l
K2 initiates the filling process.
l
K1 switches at 95% full weight.
l
At 100% fill weight, both relays return to their rest positions.

Case
open closed Mains voltage (term. 1 and 2) is present; a start signal is
triggered simultaneously (term. (5), 12 and 13).
closed open Mains voltage (term. 1 and 2) is not present or, if mains
voltage is present no
start signal is triggered (term. (5), 12
and 13).
