Code SV0385: Serial data error (separate)

Also shown as: SV0385 (15i), SV0385 (30i/31i/32i), SV0385 (0i-D) Action: CAUTION An alarm for which no action number is given is considered to be caused by a detector failure. Replace the detector. (Action) 1: Battery-related alarms Check if a battery is connected. When the power is turned on for the first time after a battery is connected, the zero battery voltage alarm is issued. In such a case, turn off the power, then turn on the power again. If the alarm is still issued, check the battery voltage. If the battery voltage decrease alarm is issued, check the voltage, and replace the battery as required. 2: Alarms that may be issued for noise If an alarm is issued intermittently or after emergency stop cancellation, noise is probably the cause. So, provide noise protection. If the same alarm is still issued after noise protection is provided, replace the detector. 3: Alarm condition detected by the separate detector If the separate detector detects an alarm condition, contact the manufacturer of the detector for information on troubleshooting. (3) Alarms related to serial communication An alarm is determined from the bits of alarms 4 and 8. Alarm 4 Alarm 8 DTE CRC STB DTE CRC STB Alarm description 1 1 1 Serial Pulsecoder communication alarm 1 1 1 Separate serial Pulsecoder communication alarm Serial communication is not performed correctly. Check if the cable is connected correctly and is not broken. If CRC or STB is issued, noise may be the cause. So, provide noise protection. If CRC or STB is always issued after the power is turned on, the Pulsecoder or amplifier control board or the pulse module may be faulty.
