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
Line resistance:
