Traulsen Power Loss Alarm

What does Traulsen Power Loss Alarm mean?

The power loss alarm tells the operator that the unit lost power. On Smart Control models the power-failure record stores the time of failure, the time power was restored, and the cabinet temperature at restart, removing guesswork about food safety. The alarm can reflect an unplugged unit, a utility outage, low incoming voltage, or a failed controller transformer.

Symptoms

• Alarm LED illuminated and horn sounding on the control
• Control display blank or recently restarted
• Stored power-failure time and restart-temperature data on Smart Control
• Cabinet temperature elevated after the outage

Common causes

• Unit not plugged in
• Loss of power due to bad weather or a utility outage
• Low incoming voltage to the unit
• Failed controller transformer

Diagnostic steps

1. 01

   Confirm the unit is plugged in

   Check that the unit is plugged in; plug it in if it is not.

2. 02

   Check for a utility outage

   Determine whether power was lost due to bad weather or an outage; full operation returns when service is restored.

3. 03

   Verify incoming voltage

   Confirm the unit is receiving correct voltage; if input is low, contact the local utility provider.

4. 04

   Check the controller transformer

   Check for a failed controller transformer per the manual procedure and replace it if it is not OK.

5. 05

   Review power-failure data

   On Smart Control units, read the stored failure time and restart temperature to judge product safety.

When to call a professional

Call a technician if the unit is plugged into a live, correct-voltage outlet but the alarm persists, which indicates a failed controller transformer. Verifying transformer output (10.2 to 13.8 volts on the listed versions) and replacing the transformer or controller require a meter and electrical service skills. Also have stored food evaluated for safety after any extended outage.
