Installation Guidelines
VIII. TESTING THE INSTALLATION
1. Self-test Diagnostics
•
The CLASSIC 800 continuously executes a self-test on its internal components and firmware. All
diagnostics are controlled by the microprocessor and are independent of the operation of the switch/
transmitter and the process conditions.
•
At initial power-on the CLASSIC 800 performs a complete self-test of all hardware and firmware. During
this test all LEDs on the Thermal Signal display will flash for approximately 2 seconds.
•
If a Fault is discovered during the self-test a Fault Code will be displayed and the relay will
de-energize. (Fault Codes are explained in
Section 7 “Troubleshooting”
).
2. Power
•
Turn on the power to the switch/transmitter and
allow the sensor to heat up and stabilize
(approximately 90 seconds)
.
•
At the conclusion of the self-test, if there is no fault condition present, the Run Mode LED will begin
flashing and a single LED (in the Thermal Signal Bar Graph) will appear on the display. As the heater
element warms up, the switch/transmitter will respond to the process conditions and this LED indicator
will move to the left.
•
Relay 1 and/or Relay 2 LEDs may illuminate depending upon the Thermal Signal, relay set point(s) and
the programmed Relay condition (set to energize ABOVE or BELOW set point).
3. Manual Test
•
Immerse the sensing tip in the actual process media by filling the pipe or vessel to the point at which the
switch/transmitter will actuate, or alternatively, into a container of the process media.
•
When the sensor is alternated between wet and dry conditions (in and out of the media), the
illuminated Thermal Signal LEDs should move and the relay set point LED(s) should change state (ON/
OFF). The degree and speed of the movement of the Thermal Signal LED depends completely on how
well the current setup of the CLASSIC 800 corresponds to the process conditions of the test.*
Note:
* Because a complete setup may not have yet been performed allow at least 20 - 30 seconds for
the sensor and relay to react when alternating between wet and dry conditions (in and out of the
media).
•
A complete explanation of setup procedures follows in
Section 4 “Setup & Operation”
and in the
Quick Setup Guide
for the CLASSIC 800.
