SOLA 4000 - PCB Description
1 UPS Control Logic
IPR front view
LD1 Parall.Operat
LD2 Red not ok
FIG. 1.6 illustrates the LEDs, potentiometers, switches and test sleeves of the IPR pcb that are accessible from the front.
-Parallel Operation On: This inverter is connected with another or more inverters to the output in parallel.
-Redundancy Not OK: Redundant units only.The load has in- creased or an inverter is off so that if this unit fails, the system must transfer to the bypass supply.
LD3 Parallel Fault
LD4 Pulse gen. Fail
-Parallel Fault: A fault has occurred with the regulation of the inverter in parallel with another inverter.
-SSI pulse generator failure: A failure or loss of synchronism has occurred within the SSI ON pulse generator. To reset press PB3 and then PB1 on the ICP pcb.

- Reference current for parallel regulation 6Vrms = nominal cur- rent of the system (0.8 p.f.).
-Inverter output current for parallel regulation 6Vrms = nominal current of this unit (0.8 p.f.).
-Difference current for parallel regulation
-Output current of this unit. 8Vdc = nominal load current of this unit (0,8 p.f.)
-System output current. 8Vdc = nominal load current on the sys- tem (0.8 p.f.)
-Redundancy current. 8Vdc = nominal load current on the re- mainder of the system (without this unit, 0.8 p.f.)
-Power of this unit. 6Vdc = nominal load power on this unit
-Power of the system. 6Vdc = nominal load power on the system
-Output voltage phase T
-Output voltage phase
-Adjust for 6Vrms at TP1 with nominal load current (0.8 p.f.)
-Adjust for 6Vrms at TP2 with nominal load current (0.8 p.f.)
-Adjust for 8Vdc at TP4 with nominal load current (0.8 p.f.)
-Adjust for 8Vdc at TP5 with nominal load current (0.8 p.f.)
-Adjust for 6Vdc at TP7 with nominal load
-Adjust for 6Vdc at TP8 with nominal load
-Manual: manual switching on/off of the inverter permitted
-Auto: inverter will automatically switch on/off depending on the load applied and the internal programming of IPR pcb.
