Section 3.. Replacement
3..(s) External Device Monitoring
Permanent Connection
After the initial checkout of Section 3.5.3 has been successfully completed, remove the EDM
bypass circuit, installed in Section 3.5.2(s). Then connect the External Device Monitoring
(EDM) input to the closed monitoring contacts of the MPCEs. Refer to the NOTICE Regarding
MPCE Monitoring Hookup, at right
.
TB2 provides connection terminals for the External Device Monitoring input (Mon a and
Mon b), and is located at the upper left corner of the control box. External device monitoring
must be wired in one of two configurations: one-channel monitoring, or no monitoring; see
Section 2.8(s).
After power is connected to the MINI-SCREEN System and the output relay contacts are
connected to the machine to be guarded, the operation of the MINI-SCREEN System 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 of the primary instruction manual.
Section 3.. Replacement
3..(s) Auxiliary Relay Output
The MSC..-1S..E controller has an Auxiliary Monitor Relay output. See Figure 5 in the primary
manual for operating status condition and output status.
The action of the Auxiliary Monitor Relay contact “follows” the action of output relays FSD1
and FSD2 in either Trip mode or Latch mode. The Auxiliary Monitor Relay contact is a
light-duty contact used for control functions that are not safety-related. A typical use is to
communicate with a programmable logic controller (PLC). The switching capacity of the
Auxiliary Monitor Relay is 125V ac or dc max., 500 mA max. Connection to the Auxiliary
Monitor Relay contact is made at wiring barrier TB4.

3..(s) Accessory Connections at Terminal Strip TB2
NOTE: The “Remote Test Input” has been replaced by the External Device Monitoring input.
See Section 2.8 of the primary manual and Section 2.8(s).
NOTICE Regarding MPCE
Monitoring Hookup
It is strongly recommended that one normally
closed, forced-guided, monitoring contact of
each MPCE be wired as MPCE monitor (as
shown in Figure 23 of the primary manual). If
this is done, proper operation of the MPCEs
will be verified. MPCE monitoring contacts
must be used in order to maintain control
reliability.
WARNING . . .
No EDM
If the application does not require external
device monitoring, the EDM input must be
jumpered. It is the user’s responsibility
to ensure that this does not create a
hazardous situation.
