Error Description Appropriate Action
DIP Switch Error
This error can be caused by
incorrect DIP switch settings or by
changes to the DIP switch settings
when the system is on. • Verify that the DIP switch settings are valid (per Section 4.1). Make any corrections
necessary and perform a receiver reset.
• If the error occurred due to a change of the DIP switch settings while the system
was in RUN mode, verify the switch settings and perform a receiver reset to resume
operation with the new switch settings and modified system configuration.
• If the error continues, replace the receiver.
EDM 1 Error
This error can occur due to EDM
1 input signal failing to respond
within 200 ms of OSSD 1 changing
state (ON or OFF) or by EDM 1
input signal changing state when
OSSD 1 did not change or by
excessive noise on EDM 1 input. • Check to see that the EDM wiring is correct and that the external devices meet the
requirements described in Section 3 .7 .
• If the error continues, remove power to the guarded machine, disconnect the OSSD
loads, disconnect the EDM input signals, configure EDM for No Monitoring (per
Section 3.7.3) and conduct the Initial Checkout procedure in Section 3.6.
• If the error clears, the problem is in the External Device contacts or wiring, or is a
response-time problem of the external devices. Check to see that the EDM wiring is
correct and that the external devices meet the requirements described in Section 3.7.
• If the error continues, check for excessive noise on the EDM inputs
(see Section 5.2).
EDM 2 Error
This error can occur due to EDM
2 input signal failing to respond
within 200 ms of OSSD 2 changing
state (ON or OFF), or by the EDM
2 input signal changing state when
OSSD 2 did not change, or by
excessive noise on EDM 2 input. • Check to see that the EDM wiring is correct and that the external devices meet the
requirements described in Section . 3 .7 .
• If the error continues, remove power to the guarded machine, disconnect the OSSD
loads, disconnect the EDM input signals, configure EDM for No Monitoring (per
Section 3.7.3) and conduct the Initial Checkout procedure (Section 3.6).
• If the error clears, the problem is in the External Device contacts or wiring, or is a
response-time problem of the external devices. Check to see that the EDM wiring is
correct and that the external devices meet the requirements described in Section 3.7.
• If the error continues, check for excessive noise on the EDM inputs
(see Section 5.2).
