ICAR PQS rev8 may1846 / 86P26.n.10 Modem call Adv (see table) OFF - MDMP26.n.11 Not shown on LCD Adv (see table) OFF - NOLCDP26.n.12 Alarm delay Adv (see table) OFF/ 1-120P26.n.13 Delay UoM Adv (see table) MIN-SECP26.n.01 - Alarm enabled - General enabling of the alarm. If the alarm is not enabled, it is as if it doesn't exist.P26.n.02 - Retained alarm - Remains in the memory even if the cause of the alarm has been eliminated.P26.n.03 - Operating mode – Operating modes where the alarm can be generated.Global alarm 1 -2 -3 - Activates the output assigned to this function.P26.n.04-05-06 - Step disconnection mode – Defines whether and how the capacitor steps must be disconnected when the alarm is present. OFF = nodisconnection, SLOW = gradual disconnection, FAST = Immediate disconnection.P26.n.08 - Slave disconnection mode – Defines, for Master-Slave applications, if when this alarm arises, the disconnection is extended to all the step of thesystem (GENERAL) or only to the output of the interested panel (LOCAL).P26.n.09 - Inhibition - The alarm can be temporarily disabled by activating an input that can be programmed with the Inhibit alarms function.P26.n.10 - Modem call - A modem is connected as configured in setup.P26.n.11 - No LCD - The alarm is managed normally, but not shown on the display.P26.n.12-13 - Delay time – Time delay in minutes or seconds before the alarm is generated.21 ALARMSWhen an alarm is generated, the display will show an alarm icon, the code and the description of the alarm in the languageselected.If the navigation keys in the pages are pressed, the pop-up window showing the alarm indications will disappear momentarily, toreappear again after a few seconds. The red LED near the alarm icon on the front panel will flash when an alarm is active.If enabled, the local and remote alarm buzzers will be activated. Alarms can be reset by pressing the key  .If the alarm cannot be reset, the problem that generated the alarm must still be solved.In the case of one or more alarms, the behaviour of the 8BGA depends on the properties settings of the active alarms.21.1 Alarm descriptionCOD ALARM DESCRIPTIONA01 Undercompensation All the available steps are connected but the cosphi is still more inductive than the setpoint.A02 Overcompensation All the steps are disconnected but the cosphi is still more capacitive than the setpoint.A03 Current too low The current flowing in the current inputs is lower than minimum measuring range.This condition can occour normally if the plant has no load.A04 Current too high The current flowing in the current inputs is higher than maximum measuring range.A05 Voltage too low The measured voltage is lower than the threshold set with P17.14.A06 Voltage too high The measured voltage is higher than the threshold set with P17.13.A07 Panel temperature too high The panel temperature is higher than threshold set with P17.06.A08 Capacitor current overload The calculated capacitor current overload is higher than threshold set with P17.08 and/orP17.09.A09 No-Voltage release A no-voltage release has occurred on the line voltage inputs, lasting more than 8ms.A10 Not usedA11 Harmonic protection Module nr. nCurrent too highThe RMS current measured by the MCP5 module n is higher than threshold set withP18.n.06.A12 Harmonic protection Module nr. nTHD-I too highThe current THD measured by the MCP5 module n is higher than threshold set withP18.n.07.A13 Harmonic protection Module nr. n5.th Harm too highThe percentage of 5.th harmonic content measured by MCP5 module is higher than thresholdset with P18.n.08.A14 Harmonic protection Module nr. n7.th Harm too highThe percentage of 7.th harmonic content measured by MCP5 module is higher than thresholdset with P18.n.09.A15 Harmonic protection Module nr. n11th. Harm too highThe percentage of 11.th harmonic content measured by MCP5 module is higher thanthreshold set with P18.n.10.A16 Harmonic protection Module nr. n13th. Harmonic too highThe percentage of 13.th harmonic content measured by MCP5 module is higher thanthreshold set with P18.n.11.A17 Harmonic protection Module nr. nTemperature 1 too highThe temperature 1 measured by the MCP5 module is higher than threshold set withP18.n.12.A18 Harmonic protection Module nr. nTemperature 2 too highThe temperature 2 measured by the MCP5 module is higher than threshold set withP18.n.13.A19 Slave xx link error The slave nr. X does not communicate with the master. Check the RS-485 wiring.A20 Clean the air filter Clean the air intake filter of the ventilation system.A21 Routine maitenance Check the currents for each step, the efficiency of the fuses and contactors.A22 Extraord.maintenance Perform the operations in A20 and A21 and check the capacitors conditions or contacttechnical support.A23 Contactors maintenance Perform the control of mechanical and electrical contactors.UAx User alarm x (x=1..8) User-defined alarm, as specified by parameters of menu M25.
