Practical Notes
Operating mode
Manual or auto start is chosen by wiring. On manual start S21 has to be
connected to ST1! via an NO push button. For auto start S21 is connected
to ST2. If both inputs are connected to S21 the unit goes into safe failure
mode. A restart or new start of the device has to be made. When selecting
the safety function 2-hand control (3), only automatic start is possible.
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 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.
Setting
On the variant /0_ _ the safety function can be set via rotary switch.
