FRONT PANEL DESCRIPTION

The front panel bezel material is

flame and scratch resistant, tinted

plastic. An optional NEMA

4X/IP65 bezel version is available

that meets NEMA 4X/IP65

requirements, when properly

installed. There are two 4-digit

LED displays, a red upper Main

Display and a lower green

Secondary Display.

There are up to six annunciators

depending on options installed,

with red backlighting, that

illuminate to inform the operator of

the controller and output status. See

Figure 11, Front Panel for a

description of the available

annunciators.

Four front panel buttons are used

to access different modes and

parameters. The following is a

description of each button.

Button Functions

DSP - In the normal operating

mode, the Display (DSP) button

is used to select one of the

operational parameters in the

secondary display or the

temperature unit’s (°F or °C). In

the Configuration Parameter

Modes, pressing this button causes the unit to exit (escape) to the normal

operating mode with no changes made to the selected parameter.

UP, DN - In the normal operating mode, the Up/Down buttons can be used to

directly modify the setpoint value or % output power (manual mode only),

when viewed in the secondary display. Otherwise, the parameter must be

called to alter the v alue.

scroll through the available parameters in any mode.
