Understanding Ingersoll Rand SSR Control Panel Warnings
The control panel on your Ingersoll Rand SSR rotary screw compressor (including models like the SSR-EPE50) does more than just start and stop the machine. It’s your first line of defense against costly downtime. Understanding the warning lights and error codes from the Intellisys controller can help you catch small issues before they become big problems.
What Is the Intellisys Controller?
The Intellisys control panel is the onboard computer that monitors and adjusts your compressor's performance. It tracks operating hours, temperature, pressure, and service intervals — and it alerts you when something’s off.
Common Warnings and What They Mean
1. High Discharge Temperature
- Usually caused by a clogged oil cooler or low coolant level
- Check for dirt or debris blocking airflow
- Inspect coolant level and top off if needed
2. High Separator Differential Pressure
- Indicates a clogged or saturated air/oil separator
- Should trigger a replacement when pressure drop exceeds 10 psi
- Also check for restrictions in the piping system
3. Motor Overload or Shutdown
- Often caused by high ambient temperatures or electrical issues
- Inspect motor cooling fans and ventilation
- Check for voltage fluctuations or loose terminals
4. Service Reminder
- Triggered at preset intervals (often every 2,000 or 4,000 hours)
- Reminds you to change filters, oil, or separators
- Resets after service tasks are logged
5. Emergency Stop Active
- Triggered manually or by a safety shutdown
- Check emergency stop button and reset circuit
- Ensure the cause of the fault is resolved before restarting
How to Respond to a Warning
When the Intellisys controller displays a fault or warning code, don’t ignore it. Log the message, power down if necessary, and inspect the area listed in the fault. Many warnings are tied to simple fixes like clogged filters or overdue maintenance.
Want to Stay Ahead of Issues?
Make a habit of checking your control panel daily. Even a quick glance can help you catch problems before they escalate. If you’re seeing the same warning repeatedly, it may be time to replace key maintenance parts like oil separators, filters, or belts.
