P3.8.4 SUPERVISION #1 LIMIT HYSTERESIS (ID 1434)Use this parameter to set the supervision limit hysteresis for the selected item.The unit shows automatically.P3.8.5 SUPERVISION #2 ITEM SELECTION (ID 1435)Use this parameter to select the supervision item.The output of the supervision function can be selected to the relay output.P3.8.6 SUPERVISION #2 MODE (ID 1436)Use this parameter to set the supervision mode.P3.8.7 SUPERVISION #2 LIMIT (ID 1437)Use this parameter to set the supervision limit for the selected item.The unit shows automatically.P3.8.8 SUPERVISION #2 LIMIT HYSTERESIS (ID 1438)Use this parameter to set the supervision limit hysteresis for the selected item.The unit shows automatically.10.9 PROTECTIONSP3.9.1 RESPONSE TO ANALOGUE INPUT LOW FAULT (ID 700)Use this parameter to select the response of the drive to an 'AI Low' fault.If the analogue input signal becomes less than 50% of the minimum signal for 500ms, an AILow fault occurs.P3.9.2 RESPONSE TO EXTERNAL FAULT (ID 701)Use this parameter to select the response of the drive to an 'External fault'.If a fault occurs, the drive can show a notification of it on the display of the drive.An external fault is activated with a digital input signal. The default digital input is DI3. Youcan also program the response data into a relay output.P3.9.3 INPUT PHASE FAULT (ID 730)Use this parameter to select the supply phase configuration of the drive.NOTE!If you use the 1-phase supply, the value of this parameter must be set to '1-phasesupport'.P3.9.4 UNDERVOLTAGE FAULT (ID 727)Use this parameter to select if undervoltage faults are saved to the fault history or not.VACON · 152 PARAMETER DESCRIPTIONS10 TEL. +358 (0)201 2121 · FAX +358 (0)201 212 205
