Configuring Auxiliary Output
Case: If your Quality Assurance requires external monitoring of System output, you can
configure the System to provide scaled output (0—20 mA or 4—20 mA)** in Power,
Amps, and Frequency modes.
Auxiliary Output is provided on the rear connector panel (TB1) as “Aux Output”.
Auxiliary Output is disabled by default.
To enable and choose an output mode:
Do this... Observe...
 From the Home zone and with the system in a
“Ready” state, select
 .
 press ► to get to
System Options.
If
System Options
was the
last feature field used, it will
appear first.
 press

again.
 use ▲ / ▼ , and scroll to
Auxiliary Out.
 press ► to scroll through output modes and
their respective scaled ranges.
Choices:

Power (0—20mA)

Power (4—20mA)

Amps (0—20mA)

Amps (4—20mA)

Frequency (0—20mA)

Frequency (4—20mA)


** = To convert 0—20 mA to 0—10 V output, a 499 ohm, 1% tolerance, 0.5W (min) metal film
resistor can be placed across the Aux Output terminals. This is best used to drive a high
impedance input on external equipment.
Note: The Auxiliary Output is updated about three times a second when the heat is on, under
internal computer control. When mains power is first applied, there is an interval of about a
second during which the computer is coming out of reset. During this time, approximately 35mA
may be seen at the output.
For more information about Auxiliary Output scaling, see “Auxiliary Output Modes and Scaling
Examples”.
