The Emergency Stop Switch
The QTERM-P40 has an optional Emergency Stop Switch
(E-stop) that can be used for triggering some external event
or device. This switch is a push-once, twist to reset, mush-
room shaped switch mounted on the front lower left side of
the terminal.
Connection to the E-stop switch is made through the inter-
face connectors on the back of the QTERM-P40. The DB9
connector has leads for the common and normally closed
switch contacts. The 10-pin terminal strip has leads for the
common, normally closed and normally open switch con-
tacts (see Table 6-1 for pin designations). This switch is
rated for a maximum of 1 amp at 30VDC.
