Hello,

After turning the Agilent 7800 ICP-MS on and starting vacuum yellow led flashes. Then stops flashing and stays still (yellow color) and software is supposed to open the gate valve, right? But gives me error-1134 (gate valve did not open). Anyone has the same experience? Pushing the little manual button gate valve opens and closes but not opening by the software. Please help.

Also I will appreciate if anyone can help to find the service manual
