A 108			RAM-backup failed			Alarm No Battery Backup Function for RAM	11104		bit 7
						Capacitor for RAM backup has discharged
						(perhaps unit has been stored for too long
						without the electronics voltage switched
						on?); load capacitor by leaving unit electron-
						ics switched on for a lengthy period.

A 110			System restart			Alarm System Restart
						Signal is filed in fault memory (fault logger),
						but not displayed at the unit or the LC-
						Display of the CDP 31x.

A 118			Mains underv.alarm			Alarm Mains Undervoltage (AC)	11104		bit 10
						Setting of undervoltage monitoring with Pa-
						rameter [P 508]
						Check: - See also Fault Code F 29.

A 120			Arm.curr.dev.alarm			Alarm Armature Current Deviation	11104		bit 13
						If the current reference [P 10405] deviates
						from the current feedback for more than
						5 sec by more than 20 %, referenced to the
						rated current, this signal will be outputted.

A 121			Ext.Overvolt.Alarm			Overvoltage protection DCF 506 has acted	11105		bit 6
						There was an overvoltage condition in the
						DC circuit of the field supply, which had been					S21.232
						limited by the activation of a free wheeling					and
						circuit.					higher
						circuit.
						Check: - Power wiring of the field supply
						- Control logic according to wiring
						example?
						- Does PP_DI_OVP [1216] has been
						connected to a binary input?
						- Setting of OVP_SELECT [1217]
						correct? (see Fault 121)

A 123			Motor 2 temp. alarm			Alarm Overtemperature MOTOR 2	11104		bit 8
						Check: - Parameter setting MOT2.TEMP_
						ALARM_L [P 1602] correct?
						See also Fault Code F 6.

A 124			Motor 2 overl alarm			Alarm Overload MOTOR 2 (Thermal Model 2)	11104		bit 9
						Check: - See Fault Code F 7.

A 126				Conv.FAN ack.alarm		Alarm No (Thyristor Power) Converter FAN	11104		bit 12
						Acknowledge
						Check: - See Fault Code F 50.
