3.4. Control Inputs
The three control inputs at terminal 10, 11 and 12 have HTL PNP characteristics.
In the COMMAND MENU the programmable functions for the control inputs can be assigned. Available
functions are: display switching, locking the touch screen or release the lock function of the control or relay
outputs.
Wiring of the control inputs:
Unconnec
ted PNP inputs are always “LOW.
All inputs are designed to receive impulses from electrical impulse sources.
Notice for mechanical switching contacts:
When exceptionally mechanical contacts are used, please connect an external capacitor between GND (-)
and the corresponding input (+). A capacity of 10 µF will reduce the input frequency to
20 Hz and miscounting due to contact bouncing will be eliminated.
3.5. Relay-Output
Two relay outputs with potential-free changeover contacts are available at terminal 27, 28, 28, 30, 31 and
32. Switching conditions can be set in the PRESELECTION MENU. The switching states are displayed
(display with unit and status bar) as K1 and K4.
AC-switching capacity max 250 VAC/ max 3 A / 750 VA
DC-switching capacity max 150 VAC/ max 2 A / 50 W
