Electrical Installation
The electrical installation is only to be performed by specialized personnel. During
installation it has to be observed that supply and signal lines have to be installed separately
from power lines. Inside the switching cabinet, suitable spark extinction has to be provided
if using contactors. In connection with driving motors and breaks, the corresponding
manuals have to be observed.
5.1
Supply Wiring
The test monitoring unit TMC 66 is supplied with 24V DC +/-15%. Current consumption is
max. 200 mA (without active muting light signals).
5.2
Start Input Wiring
Within the operating modes with/without start- and restart interlock, the start input works in
two possible ways:
• In the operating mode with start- and restart interlock, the TMC 66 expects two signal
changes (push-button function) as switch-on signal. A failure in the start button, e.g. due
to contact malfunction is safely detected by the TMC 66.
