Figure 4: External GND only

Fault sequence:

•

Fault

①

(defective protective component):

A component connected to GND on the output short circuits or behaves like an ohmic resistor. This fault

is not always detected.

•

Fault

②

(open circuit on module GND):

The module loses its direct connection to GND and current begins to flow through the defective protective

component → I

OUT

→ actuator.

As a result, current above the maximum value permitted by the module is supplied to the actuator.

Danger!

This type of installation can cause hazardous situations and is therefore NOT permitted.
