I.Control Electrical System

CAUTION: When servicing the HIGH VOLTAGE section of the dryer, the ELECTRIC SERVICE MUST BE DISABLED. THE "EMERGENCY STOP" BUTTON DOES NOT DISABLE THE HIGH VOLTAGE TO THE DRYER.

1.Control Electrical System Description

a.3-Phase (3ø) Electrical Power

The 3-phase (3ø) electrical power for the dryer enters the dryer through the power distribution block located in the dryer base electrical box. It is then distributed to the blower (impellor and fan) motor, drive (tumbler and basket) motor, and control circuits.

1)Blower (squirrel cage fan) Motor

The blower (impellor and fan) motor circuit consists of a blower motor thermal magnetic overload. The overload current is adjustable by a dial located on the face of the overload. (Refer to the electrical specification diagram for correct current setting.)

Attached to the thermal magnetic starter is an auxiliary contact used to sense an overload trip. This produces a safety error so the dryer service is disabled (the dryer will not start).

In series with the thermal magnetic overload is the blower motor contactor. This device enables the supply voltage to reach the blower (impellor and fan) motor. The blower motor contactor is controlled by the Phase 5 microprocessor controller (computer). When 24 VAC is applied to coil A1-A2, the contactor closes and enables the circuit.

The blower (impellor and fan) motor used for ADG-200 gas model dryers is 7-1/2 HP (horsepower) and for ADS-200 steam model dryers is 15 HP (horsepower) . The motor wiring configuration is dependent on the specific voltage of the dryer. When wiring the motor, refer to the motor nameplate.

2)Drive (tumbler/basket) Motor

The drive (tumbler and basket) motor converts the 3-phase (3ø) power source entering the drive motor thermal magnetic overload. The overload current is adjustable by a dial located on the face of the overload. (Refer to the electrical specification diagram for correct current setting.) In this circuit, the drive motor contactor follows the thermal magnetic overload.

The drive motor has two (2) separate sets of coils and two (2) separate sets of contacts. One (1) of these sets is for forward tumbler (basket and drum) rotation and the other for reverse tumbler (basket and drum) rotation. The thermal magnetic overloads and the contactors are located in the left hand electrical cabinet. The direction of the drive motor is determined by the phases going into the motor (i.e., in a reverse direction phase, L1 and L2 are switched). When viewing this contactor, the left hand block connections are for the forward rotation direction (clockwise [CW]) when viewed from the front of the dryer.

The drive (tumbler and basket) motor is a 3 HP (horsepower) motor. Refer to the motor nameplate for specific terminal box wiring.

AD-200 specifications

The American Dryer Corp AD-200 is a renowned commercial dryer that stands out in the market for its efficiency, performance, and durability. Designed for high-demand environments such as laundromats, hotels, and gym facilities, the AD-200 delivers robust performance while maintaining user-friendly operation.
