LED Indicators

The two-color LED display indicating operating status can be viewed by opening the

cover of the electronics module.

Table 3. LED Display.

LED Display Status Description

LED green On continuously Automatic mode: Auto (normal, no faults)

Flashing – Mechanically set to MANUAL

– Mechanically set to OFF

– Currently in auto-calibration mode

LED red On continuously – General fault

– General calibration fault

– Microcontroller fault

Flashing – Faulty 24 Vac supply (that is, too low)

LED Off – No 24 Vac supply

– Fault with electronics module

As a general rule, the LED can only assume the conditions in Table 3 (continuously red

or green, flashing red or green, or off).

Mounting

Mounting and operating instructions are printed on the actuator and on the electronics

module.

The valve is suitable only for straight-through or three-way applications and may be

installed only in a mixing arrangement. In the case of the straight-through valve, strict

observance of the direction of flow is essential.

Do not mount with actuator below horizontal position.

Access for Mounting

It is essential to maintain the specified minimum clearance above and to the side of the

actuator and/or electronics module for servicing, installing and heat dissipation:

• 1/2-inch to 1-1/4 inches = 4 inches

• 1-1/2 inches to 2-1/2 inches = 6 inches
