Enabling Switches

The electronic enabling switch realizes the enabling equipment as a safety function

for machines in special operating modes. The enabling switch is part of the

MobileView terminal.

Each machine features a normal operating mode and a special operating mode.

• In normal operating mode, guards and/or operative protection devices are

used to prevent access and guarantee safety. Special operating modes are

used to maintain the normal operating mode.

• The device meets safety class III in accordance with EN

61131-2 and EN 50178. The 24V power supply for the

equipment must provide appropriate isolation between

safety-extra-low-voltage circuits and dangerous-contact

voltage circuits (for example, by safety transformers or

similar facilities).

• Protect the power supply circuit with a 3.15 A fuse.

• The nominal supply voltage of the MobileView terminal

(without Mobile View Connection Cable) is +24V dc

(supply voltage range: 18 to 32V dc).

Typical current consumption is:

- 300 mA at 24V dc

-400 mA at 18V dc

When planning the power supply, consider the voltage

drop on the MobileView Connection Cable.

Specifications of power supply lines in this cable are:

Cross section: AWG24 (0.24 mm

Material: zinc-coated copper strand
