What does the Service Plan message mean on a Quincy QGD compressor?
Short answer: Service Plan interval reached. If your Quincy QGD 40-60 / QGS 40-100 (Airlogic2 controller) is showing Service warning (Service Plan message), the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
Service operations are grouped into Service Plans with programmed hour intervals; when the service timer passes a plan's interval, the display warns the operator to carry out that plan's maintenance and the service LED lights.
Which machines show this?
Quincy QGD 40-60 hp and QGS 40-100 hp rotary screw compressors with the Airlogic2 display controller, including Full Feature packages with the integrated refrigerated dryer. Like Quincy's smaller INFOLOGIC machines, these display icons and text messages, not numbered fault codes — a lit alarm LED means a warning, a flashing one a shutdown, and the specific condition is spelled out on the controller's screens and logged in the Event History menu. Warning and shutdown levels for temperatures are programmed values with factory settings, so your machine's exact trip points can differ. Two habits the manual insists on: the emergency stop does not make the machine voltage-free, and service timer changes go through the authorized distributor.
What causes it?
- The service timer passed a Service Plan's programmed hour interval
- A maintenance reminder, not a fault — the Service menu shows which plan is due
Can you fix it yourself?
Yes — lock out power, let the unit cool, do the due consumables (air filter, oil filter, separator, oil as applicable), and reset the message on the controller.
Step by step — what to try, in order:
- Open the Service menu to see which Service Plan is due
- Stop the unit, switch off and lock out power, and let it cool
- Perform the due consumable maintenance per the preventive maintenance schedule (air filter, oil filter, separator, oil as applicable)
- Reset the service message via the controller after servicing
When do you need a technician — and why?
Anything past routine consumables — and any change to the timer settings themselves — goes through the authorized Quincy distributor per the manual.
