TESTS EXPLANATION
HG-1-1401A
(For software version 3.0 and later)
PRELIMINARY:
To test a new installation, first check that all necessary connections for electrical,
water, gas and drain are made. Standard 3-phase electrical power supplies are
480VAC 60 HZ, 415VAC 50 HZ, or 380VAC 50 HZ.
With electrical power off, prepare to purge the gas line of debris and air by closing
off the gas supply valve before the Gas Pressure Regulator (GPR) and having the
main gas supply on. Open the pipe cap on the end of the short pipe debris trap nipple
under the regulator and quickly open/close the gas supply valve several times. Debris
in the pipe will blast out. Keep doing this until gas is noticeable. Make sure good
ventilation is present and no one is smoking.
Check that power on terminals 1 and 2 on the electrical panel is between 103 and 125
VAC.
TO ENTER TESTS PROGRAM
-- The TESTS program is run from the diagnostic
module display DMD at the local panel. 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.
