Enabling Grip Switch - Reer MZERO Installation, Use And Maintenance Manual

ENABLING GRIP SWITCH

The ENABLING GRIP functional block checks the status of the In
inputs of an enabling grip. If this is not gripped (position 1) or is
gripped completely (position 3), the OUTPUT will be 0 (FALSE). If it
is gripped to middle position (position 2), the OUTPUT will be 1
(TRUE).
Refer to truth tables at the bottom of the page.
Parameters
Type of inputs:
with 2 NO contacts.
-
Double NO+1NC – Permits connection of an enabling grip
-
switch with 2 NO contacts + 1 NC contact.
Test outputs: Permits selection of the test output signals to be sent
to the enabling grip.
This additional control permits detection and management of any
short-circuits between the lines. To enable this control, the test
output signals must be configured (amongst those available).
Power-on test: If selected, enables the power-on test of the
external component (Enabling Grip). To run the test, the device must be gripped and released to
carry out a complete functional check and enable the Output terminal. This control is required
only at machine start-up (power-on of the module).
Simultaneity (ms): always active. Determines the maximum permissible time (ms) between
switching of the various signals from the external contacts of the device.
Filter (ms): Permits filtering of signals from the device control. This filter can be set to between 3
and 250ms and eliminates any rebounds on the contacts. The duration of the filter affects
calculation of module total response time.
Table mode 1 (device 2NO + 1NC)
Table mode 1 (device 2NO + 1NC)
Enable Error Out: If selected reports a fault detected by the function block.
Item description: Permits insertion of a descriptive text of the function of the component. This text
will be displayed in the top part of the symbol.
