Wiring Shadow 8 to EDM Monitor Inputs
External Device Monitoring (EDM), also called Machine Primary Control Element (MPCE)
monitoring, is an important safety function. EDM monitors the Shadow 8 interface to the
guarded machine, checking to make sure that the interfacing relays are responding correctly to
the light curtain and that there is no inconsistency between the state of relays and that of the
Shadow 8 safety outputs.
Connections for EDM monitoring are made at the terminals labelled “EDM” and “0 Vdc” on
terminal block TB3 on the Main board in the optional Shadow 8 control box (see Figure 2-20,
page 2-32). To enable EDM monitoring, you must set switches SWA 2 and SWB 2 on the
Main Receiver to “ON” (see Enabling External Device Monitoring (EDM) (Receiver Switch
2), page 2-47) and set switch SW1 EDM on the Main board in the control as follows:
•
If the optional control is wired directly in series with the machine’s E-stop circuit without
any external relays, set SW1 EDM to “INT” (see figure 2 at the back of the manual)
•
If the optional control is wired to external relays, set SW1 EDM to “EXT” (see figures 3
and 4 at the back of the manual)
•
If the optional control is wired to a Wintriss Clutch/Brake Control (see Wiring Shadow 8
Optional Control to a Wintriss Clutch/Brake Control, page 2-43), set SW1 EDM to “INT”
(see figures 5 through 9 at the back of the manual).
When Shadow 8 heads are wired directly to a Wintriss Clutch/Brake Control (i.e., there is no
optional control box), the EDM function must be disabled by setting SWA 2 and SWB 2 on
the Main Receiver to “OFF” (see figures 11 through 13 at the back of the manual).

ENSURE THAT EDM INSTALLATION IS SUITABLE FOR SAFETY USE
• Install EDM relays in pairs as instructed in this manual (see figures 3 and 4 at end of manual).
• Use only relays with forced guided type contacts for EDM monitoring.
• Ensure that the response time of the EDM circuitry is 300 mS or less.
• Use only the safety outputs for personnel protection.
Failure to comply with these instructions will result in death or serious injury.
