Enabling Grip Switch - Reer MOSAIC Master M1 Installation And Use Manual

MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC

ENABLING GRIP SWITCH

The ENABLING GRIP functional block checks the status of
the In inputs of an enabling grip. If this is not gripped
x
(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.
The ENABLING
that the assigned module has a minimum Firmware
version as Table below:
M1 MI8O2
1.0 0.4
Parameters
Type of inputs:
Double NO – Permits connection of an enabling grip
-
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 that maximum permissible time (msec)
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 250 ms and eliminates any rebounds on the contacts. The duration of the
filter affects calculation of module total response time.
