Description

 

 

 

 

 

 

 

PV

Process Value

 

During normal operation, the process value (PV)

 

 

 

 

Numeric LED

 

numeric LED indicator displays the process

 

8.8.8.8

 

 

 

 

 

 

temperature at the To Process thermocouple. It

 

 

 

 

 

 

 

 

 

 

 

 

also lists parameters during setup and error

 

 

 

 

 

 

messages if any errors occur.

 

 

 

SV

Set Value

During normal operation, the set value (SV)

 

 

 

 

Numeric LED

numeric LED indicator displays the process set

 

8.8.8.8

 

 

 

 

 

 

point temperature selected for the dryer. The dryer

 

 

 

 

 

 

 

 

 

 

then maintains this set point temperature. This

 

 

 

 

 

LED indicator also displays parameter and pre-set

 

 

 

 

 

function values during configuration setup.

 

 

 

 

OUT1

Out 1 LED

 

Lit when Control Output 1 is on. The Out1

 

 

 

 

 

 

indicator lights when the controller signals the

 

 

 

 

 

 

process heaters to be energized.

 

 

 

 

OUT2

Out 2 LED

 

Lit when Control Output 2 is on. Not used in

 

 

 

 

 

 

this application.

ALARM1

ALARM 1 LED

 

Lights in the Operation Indicator Section when

 

 

 

 

 

 

the output function assigned to auxiliary output

 

 

 

 

 

 

1 turns on. The ALARM1 indicator lights when

 

 

 

 

 

 

the process temperature exceeds the set point

 

 

 

 

 

 

temperature by more than the alarm deviation

 

 

 

 

 

 

value.

Press the Mode key to shift the display to the next

 

 

 

 

 

 

set of parameters. The menu screen displays.

 

 

 

 

 

 

 

 

 

 

Down Key

Press the Down arrow key to lower the process air

 

 

 

 

 

 

set point temperature. During setup, it lets you

 

 

 

 

 

 

decrease the value of the parameter displayed on

 

 

 

 

 

 

the set point LED readout.

 

 

 

 

 

 

 

 

 

 

 

Up Key

 

Press the Up arrow key to raise the process air set

 

 

 

 

 

 

point temperature. During setup, it lets you

 

 

 

 

 

 

increase the value of the parameter displayed on

 

 

 

 

 

 

the set point LED readout.
