Single-Channel Control
Single-channel (or one-channel) control, as mentioned, uses a series connection
of FSD contacts to form a safe switching point. After this point in the machine's
safety-related control system, failures can occur that would result in the loss of
the safety function (e.g., a short-circuit to a secondary source of energy or volt-
age).
Thus, this method of interfacing should only be used in installations where FSD
safety stop circuits and the MPCEs are physically located within the same control
panel, adjacent to each other, and are directly connected to each other; or where
the possibility of such a failure can be excluded. If this can not be achieved, then
two-channel control should be used.
Methods to exclude the possibility of these failures include, but are not limited to:
• Physically separating interconnecting control wires from each other and from
secondary sources of power.
• Routing interconnecting control wires in separate conduit, runs, or channels.
• Routing interconnecting control wires with low voltage or neutral that can not
result in energizing the hazard.
• Locating all elements (modules, switches, devices under control, etc.) within
the same control panel, adjacent to each other, and directly connected with
short wires.
• Properly installing multi-conductor cabling and multiple wires that pass through
strain-relief fittings. Over-tightening of a strain-relief can cause short-circuits at
that point.
• Using positive-opening or direct-drive components installed and mounted in a
positive mode.

3.8 Commissioning Checkout

After power is connected to the MM-TA-12B Muting Module, the EDM has been
properly configured, and the OSSD outputs have be connected to the machine to
be guarded, the operation of the MM-TA-12B Muting Module with the guarded
machine must be verified before the combined System may be put into service.
To do this, a Qualified Person must perform the Commissioning Checkout
Procedure described in Section 6.2.
