Power-up Check
After the TDC5 is
connected to an
appropriate AC voltage
source, you can turn it on
to verify its basic operation.
The power switch is a large
rocker switch on the left
side of the rear panel.
When the TDC5 is powered up, the temperature controller should light up and display a couple of status
messages. Each message will be displayed for a few seconds.
If you connected an RTD to the unit, the upper display should show the current temperature at the probe (the
units are degrees Celsius). If you do not have a probe installed, the upper display should show a line containing
the characters
oPER
, as shown below:
Once the unit has powered up correctly, turn it off before making the remaining system connections.
Make sure that a newly installed TDC5 has no connection to its switched
OUTPUT
outlets
when it is first powered. You want to verify that the TDC5 powers up correctly before you add the
complexity of external devices.
Warning:
If you replace the line cord you must use a line cord rated to carry at least 10
A of AC current. An improper line cord can create a safety hazard, which could result in injury or death.
