Rear seal wash leaking error

Issue

Chromeleon keeps reporting “Error 61: Rear Seal Wash Sensor Malfunction” but no rear seal wash sensor is actually installed.  

Environment

• ICS-6000 Pumps
• ICS-5000⁺ Pumps
• ICS-5000 Pumps
• Chromeleon

Resolution

1. Go to Chromeleon workstation and navigate to “Instrument”.
2. Click command button or click F8 on the keyboard to activate the instrument command window.
3. Under “Pump_1”-“Properties”-“RearSealWashSystem”, change “Automatic” to:
   1. "Interval" if running eluent other than water through the pump head, that is, manually prepared eluents.
   2. "Off" if running water only through the pump head, that is, eluent generation.
