Rocketronics ELS 4 Basic, Operating Instructions Manual

Page: 34 / 106

NOTE
All inputs are deactivated at the factory and must first be activated in the settings!
When activating the ESTOP input, make sure that you have a possibility to connect the ESTOP
input, otherwise the control may be blocked! The ESTOP input is OPEN ACTIVE ex works (NC
- „Normally Closed“). The inputs ZLIM, XLIM and ERROR are CLOSED ACTIVE (NO- „Normally
Open“). The switching polarity can be changed for each input in the settings, see SETTINGS ->
INPUTS.

The controller has 4 digital inputs that can be loaded with up to 12V. For easy connection, 12V
is available next to each input terminal. If external power supplies are used, the earth terminals
next to the input terminals can be used for the earth connection between the power supply
and the controller. The inputs draw approx. 5mA current at 12V.
Terminal assignment:
Both normally closed and normally open contacts can be used, or inductive proximity switches
(PNP or NPN, 12V!). Terminals 9 and 10 (GND) can be used to connect the control ground to
external power supplies or sensors.
Input 1: ESTOP
The input must be activated in the settings! Input for emergency stop signal. Connect a po-
tential-free contact here, e.g. an emergency stop mushroom button or a relay contact of the
emergency stop circuit. When the contact is opened, the control unit switches to a safe state.
If the ESTOP input is activated and the state is tripped, the controller blocks; release can only
take place after the emergency stop state has been eliminated! If the switching contact closes
(NO) in the event of tripping, the polarity must be changed in the settings! See also EMERGENCY
