Heater 'Burnout' Detector

Single and 3-phase

Stalled Motor Detector
Self powered (When current is above 5A) 

BO Detector Series Burned out heater elements cost time and money to diagnose. Don't let them cost you down time. Get the Burnout detector! Unique self-powered design saves complexity and wiring time.  The burnout detector works by sensing the AC current and activating at the specified set point. Sensing a repeatable specific trip-point, allows the burnout detector to monitor multiple parallel connected heater elements. The BO series can detect stalled motors by sensing the out of range current. In 3-phase operation (using a delta or 4-wire-Y configuration), of the Transtronics Burnout detector allows one sensor to monitor all three phases. Upon detection, it lights the LED and optionally activates an output.  Four basic output versions are available: LED lamp only, open collector, Triac and form C relay. Options include: large pass opening, adjustable set-point and remote mounting LED.

Applications:

Standard 0.875" Opening

• Plastic Extrusion Injection Molding
• Tank Heaters
• Process Heaters
• Stalled Motor Detector
• Load Shedding
• Dust collectors

[] - denotes legacy units

Operation

• In single-phase configurations, LED and optional outputs are active on normal operation.
• When applied in both the Delta and 4-wire-Y 3-phase configurations, LED and optional outputs are active on heater failure.
• The calibrated set point allows sensing of single element failure in parallel connected heater elements in both single and 3-phase installations.
• The Delta configuration requires three wires threaded through the sensor; make sure you have enough room.
• The 4-wire-Y 3-phase configuration provides a simple neat installation with minimal wiring.

Optional 1.25" Opening order -LD

Wiring Diagrams

One or 3 Wire(s) with Ac current are threaded through opening.
No electrical contact is made with the current carrying wire

Remote mount LED wiring Pin 2 goes to + (plus) or the long lead
Pin 4 goes to - (minus) or the short lead. No dropping resister is required
Remote mount LED is not compatible with Triac version 

Din rail mountable bases are available as an accessory
