Terminal strip X6 in the control device
At the terminal strip X6, wiring between the control device A70 and the control cards A1, A3 and
A5 of the power section is performed by the works. Allocation of the terminal strip is as follows:
X6 Name
11 thyristor L1 neg.
12 +5V
13 thyristor L1 pos.
21 thyristor L2 neg.
22 +5V
23 thyristor L2 pos.
31 thyristor L3 neg.
32 +5V
33 thyristor L3 pos.
41 input temperature sensor
42 ground temperature sensor
TAB. 20 TERMINAL STRIP X6
Each thyristor is controlled by 20mA current supply switching to ground.
The ventilator monitor is connected to the terminals X6.41 and X6.42 in separately ventilated
devices (..HF). The temperature of the power section is monitored using a PT 1000 temperature
sensor. In case of overheating of the power section, for instance caused by outage of the ventilator,
a fault indication is generated and the alarm relay is activated (default values). The temperature
may be enquired by the interfaces.
