STVS1
230 VAC TRANSFORMER CONTROLLER WITH
ANALOGUE INPUT
6.4
If applicable, connect the unregulated output (L1 and N). It can be used to
supply a 230 VAC valve, lamp, etc. when the knob is not at ‘0’ position (see
Table 1
below).
6.5
Connect the TK contacts for monitoring of the thermal motor protection
to the motor TK terminals. As standard, there is a bridge between the TK
terminals.
6.6
If applicable, connect the 12 VDC digital output (+V terminal) for fault
indication (0V = TK fault; 12 V = normal operation)
ATTENTION
A safety isolator / disconnect switch should be installed on the mains electricity
side of all motor drives.
