Thank you at advance for all of you.I have abig problem at mentioned unit.The unit was installed after storing 4 years.I think It was installed well.I tried to start the unit at diesel engine option .Although the unit is sleep,I found two alarms at SR-2 controller.the first is :high discharge pressure.The second alarm:the diesel engine at low speed.I pushed Clear bottom to cancell alarms but no clearing and consequently no starting for the unit.Please inform me what can I do?Thanks
