5.4 ■ Setup Watlow Series F4S/D

Retransmit Output 1

To track the temperature of the

equipment inside the chamber,

Andy configured a retransmit out-

put to match input 3. He scrolled

down the list of inputs and outputs

on the Setup Page and found Re-

transmit Output. He chose 50ºF

and 150ºF, respectively, for the

Scale Low and Scale High; the

smaller the range, the higher the

resolution on the chart.

Source: Input 3

Current: 4-20mA

Scale Low: 50°F

Scale High: 150°F

Scale Offset: 0°F

Control Output x

(1A, 1B, 2A, 2B)

Next, he scrolled back up to

set the control outputs con-

trolling heat and humidity.

For the fastest possible

switching rate, tighter control

and longer heater life, he se-

lected Burst Fire control for

each of them, designating 1A

and 1B as heat/cool outputs,

and 2A and 2B as

humidify/de-humidify outputs.

Analog Input 1

For greatest accuracy in measuring the chamber temperature, a re-

sistance temperature detection (RTD) sensor has been wired to ana-

log input 1. Andy wanted to measure tenths of degrees Fahrenheit,

with an alarm that would clear by itself if the temperature exceed-

ed or fell below the active alarm set point band. Alarm set points

are determined in the Operations Page.

Sensor: RTD Set Point High: 450.0°F

Type: DIN No Calibration Offset

Decimal Point: 0.0 0-second Filter

Set Point Low: 32.0°F Self-Clearing Error

Digital Output 7

Digital output 7 was wired to an SSR (solid-state relay) that switch-

ed a solenoid valve controlling the flow of liquid nitrogen used for

cooling.

Name: Default

Function: Boost cool

Boost Power Level: -90%

Boost Delay: 20 seconds

Before programming the profile

to run the temperature and hu-

midity tests in the environmen-

tal chamber, Andy had to con-

figure the controller to suit the

equipment and the test.

He went to the Setup Page,

System Menu, and established

the global system parameters,

including the real-time clock,

the date and the PID units.

Then he continued through the

list of inputs and outputs, con-

figuring each and keeping

notes about his settings on the

User Setup Chart.

To enter, press the Right

Key.

To exit, press the Left Key

repeatedly.

Use a copy of the chart at

the end of this chapter to

record your settings.
