Practical Notes

Operation mode
With the potentiometer on the front plate the operartion mode can be
adjustet. The adjustment must be required before energizied. Adjustment
during energization is not allowed.
Only an automatic start at safety function two-hand control (3) is possible.

button
Fkt. 1:
For manual start S21 must be connected via a pushbutton to ST1. For auto
start S21 has to be linked to ST1
Fkt. 2:
For manual start S41 must be connected via a pushbutton to ST2. For auto
start S41 has to be linked to ST2.
Line fault detection e.g. monitoring of ON-button
If the On-button pressed more than 3 s the adequate output contacts of the
safety function can't be switch. The output contacts can be energized when
the On-button pressed again (0.1 s < t
A line fault is detected if the On-button more than 10 s is actuated. The
output contacts of the adeauate safety function can only be energized with
a reset or re-start with on an off switching of power supply.
Reset and external failures:
The reset input is used to reset external failures (application failures or
removable external failures as e.g. a line fault on reset button). If the reset
signal is connected to the input for more than 3 sec the unit unit makes a
reset. A new reset is only possible when the reset signal had been switched
off temporarily.
If an external failure occurs because both input channels of a safety function
did not switch on or off within the simultanious time, a reset is only possible
if both channels are switched to off state after removing failure cause.
If an external failure occurs in only one safety function, only this function
will be disconnected. The second safety function still continuous to work.
Function setting
The variants with selectable safety functions have 2 potentiometers Fkt.1
and Fkt.2 to select the required function. The following functions are possible:
