Output signal of local Emergency Stop pushbutton (OPTIONAL)
In the standard units, there is no readback signal of the position of the local Emergency Stop
pushbutton located in the front panel. On request (OPTION), it is possible to add a Normally
Closed output contact of the front panel Emergency pushbutton.
In this case, the Emergency Stop pushbutton installed on the front panel of equipment has two
normally closed (NC) output contacts: one NC contact is used for the internal emergency
sequence of the equipment; and the second NC contact is wired to the lower front of the
equipment, along with the connection power terminals.
The additional contact could be used by the customer to integrate CINERGIA equipment into the
Emergency Power Off sequence of the installation.
