Technical leaﬂet Fan Speed Controllers, Type RGE

Introduction Saginomiya type RGE condenser fan speed

controllers are compact, robust phase controllers designed for application on condensing units and packaged air-conditioning systems. They are particularly suitable in units that operate the year around, and provide stable operation with constant condensing pressure during winter or moderate seasons. RGE controllers make possible cost-ecient variable control of fan speed.

Features

Pressure sensing element integrated. Sensor-bellows structure provides high

reliability Single phase and 3 phase versions available. All common refrigerants R22, R407C, R404A,

R134a, R410A Designed for reduced-noise operation Selectable slowdown mode or cut-o mode ¼” female connection with schraeder

depressor pin Terminal for an external forced operation

switch is provided. IP54 enclosure CSA-us approved CE and EMC

Adjusting Method

1) Range adjustment Setting point is increased by turning the range adjusting screw clockwise. It is decreased by turning the screw counter-clockwise. Adjustment should be within the range indicated for the setting pointer.

2) Lower pressure operation selection Following operation are selectable with the change-over switch. Minimum speed running : Fan motor operates at the Minimum speed when the pressure decreases below the value “Pmin”. Cut-off : Fan motor stops when the pressure decreases below the value “Pmin”.

Pmin = F.V.S – E.B.P. F.V.S = Pressure setting for max. speed (Adjustable) E.P.B = Effective Proportional Band (Fixed)

Wiring

Installation

1. Mount on ﬂat surface with conduit connection downward.

2. Connect the pressure sensing element so as to sense head pressure.

3. If installing the controller outside the unit housing, protect human hand from direct touching.

4. Do not use RGE with ammonia systems.

5. Connect RGE only to fan motor.

6. Operate only with cover in place.

7. Turn off the power supply before adjusting the setting or operating the change-over switch.
