Table 1101: Error messages for safety I/O modules (channel or module reintegration is possible)
Severity	Error code	Description	Remedy
3	3	Discrepancy time expired	Check discrepancy time value, channel wiring and sensor.
3	12	Test pulse error	Check wiring and sensor.
3	13	Channel test pulse cross-talk error	Check wiring and sensor. If this error persists, replace I/O module. Contact ABB technical support.
3	25	Channel stuck-at error	Check I/O module wiring. Restart I/O module, if needed. If this error persists, replace I/O module.
3	28	Channel cross-talk error	Check I/O module wiring. Restart I/O module, if needed. If this error persists, replace I/O module.
3	260	Measurement overflow at the I/O module	Check channel wiring and sensor power supply.
3	263	Measurement underflow at the I/O module	Check channel wiring and sensor power supply.
3	311	Channel value difference too high	Adjust tolerance window for channels. Check channel wiring and sensor configuration.
3	525	Channel readback error	Check I/O module wiring. Restart I/O module, if needed. If this error persists, replace I/O module.
3	530	Channel cross-talk error	Check I/O module wiring. Restart I/O module, if needed. If this error persists, replace I/O module.
3	16138	Process voltage too high	Check process voltage
3	16139	Process voltage too low	Check process voltage
3	16148	PROFIsafe communication error	Restart I/O module. If this error persists, contact ABB technical support.
3	16153	PROFIsafe watchdog timed out.	Restart I/O module. If this error persists, increase PROFIsafe watchdog time.
3	16171	Internal error in the device	Replace I/O module

Table 1102: Error messages for safety I/O modules (channel or module reintegration ist not possible)
Severity	Error code	Description	Remedy
3	16146	Plausibility check failed (iParameter)	Check configuration
3	16147	Checksum error in the I/O module	Check safety configuration and CRCs for I- and F-Parameters.
3	16154	Parameter value	Check master or configuration
3	16156	F-Parameter configuration and address switch value do not match.	Check I/O module F-Parameter configuration and module address switch value.
