Installation

3.3 Installation in combination with VLT

PTC Thermistor Card MCB 112

NOTICE!

Combination of VLT

STO function is only available for VLT

102, VLT

AutomationDrive FC 302, and VLT

AutomationDrive FC 301 enclosure type A1.

VLT

PTC Thermistor Card MCB 112 uses Terminal 37 as its

safety-related switch-off channel.

•

Ensure that the output X44/12 of MCB 112 is

AND-ed with the safety-related sensor (such as

emergency stop button, safetyguard switch, etc.)

that activates STO. This means that the output to

STO terminal 37 is HIGH (24 V) only if both the

signal from MCB 112 output X44/12 and the

signal from the safety-related sensor are HIGH. If

at least one of the two signals is LOW, then the

output to terminal 37 must be LOW too.

•

Ensure that the safety device with AND-logic

complies with the needed safety level.

•

Short circuit protect the connection from the

output of the safety device with safe AND-logic

to the STO terminal 37, see Figure 3.3.
