This AMETEK Rotron Explosion-proof Regenerative Blower may be equipped with Pilot Duty

Thermal Overload (PDTO) or Automatic Thermal Overload (ATO) protection. When properly

wired to a motor starter, this protection limits the motor winding temperature rise per the

National Electric Code (NEC) article 500. Failure to properly wire this blower is an NEC

violation and could cause an explosion. AMETEK Rotron assumes no responsibilities for

damages incurred by negligent use of this product, and will not warranty a blower on which the

PDTO is not properly connected. Some blowers 1 HP and under do not require PDTO and

have built in ATO. Consult the factory if verification of wiring connections is required.

In all cases, follow the motor controller manufacturer's instructions. The following schematic is

for conceptual understanding only, and may not apply to all motor/controller combinations.

The manufacturer's wiring diagram found on the motor takes precedent over reference

diagrams supplied by AMETEK Rotron Technical Motor Division.

Motor

The schematic is shown for a

three phase motor. For a

single phase motor disregard

L3 and M3. Pushing the

START button completes the

auxiliary control circuit,

allowing current to flow

through the magnetic coil.

The contacts are

magnetically closed, starting

the motor and latching the

auxiliary circuit. The motor

will continue to run until the

STOP push button is

depressed, the motor

reaches the overload

temperature, or the current

sensing overloads trip out.
