TO ENTER TESTS PROGRAM
The TESTS program is run from the Diagnostic Module Display DMD at the Local Panel
LP. TESTS is used at the factory on the test stand, used at commissioning time, and used
to help troubleshoot the heater in the future. TESTS can only be accessed when the heater
is off and not during the heater’s normal gas leak test. To access TESTS when the heater
is doing its leak test, power cycle the panel.
To enter TESTS, turn the +/- selector switch until the blinking cursor is on TESTS. Press
the SELECT button to enter TESTS. Use the +/- selector switch to maneuver through the
various test selections. Press the SELECT button to choose the test you want to perform.
Unlike earlier Samuel Jackson combustion products with PLC’s where the test program
had to be done in sequence, this TESTS program allows the user the choice of which tests
to perform. Observe the display for test program prompts.
TO EXIT TESTS PROGRAM
To exit TESTS at any time, turn the +/- switch until BACK is displayed, then press the
SELECT button. Killing the supply power will also exit the test program.
Following are the TESTS selections that are available with descriptions of each.
BACK -- Pressing SELECT button when BACK is displayed exits the TESTS program.
INPUTS -- Observe the condition of PLC inputs. The alphanumeric displays ON and
OFF status of inputs. If input status is not correct, the input number will flash on the
displays until corrected. The operation of the local start-stop switches (and optional
remote start-stop switches) and other inputs can be tested while observing the displays or
the input LED indicators on the PLC. Press SELECT to proceed. If inputs are not
correct, advancing out of this test will be prohibited. If the problem is understood and
bypass is desired, press and hold SELECT button for 3 seconds to advance. If input 6
(X106 for Gas Low Pressure switch GLPS) is blinking, turn the +/- switch to –
momentarily to open Pilot Valve (PV) to relieve the gas pressure.
