This phase of testing pertains to the components associated with preheat functions.
After completing Phase 1 Testing, verify that the following conditions are set to
start Phase 2 testing:
• The right side and front access panel are removed and the float
assemblies, relays and contactors are clearly visible.
• The Main Disconnect Switch is in the ON position and the 3-minute
blowdown cycle has stopped.
• The ON/OFF power switch is in the OFF position.
• Both upper and lower compartment TIMED/MANUAL switches are in
the TIMED position.
• Both upper and lower compartment timers are set for zero minutes.
a. For Key Pad Control Panels: The timer display is blank while the
ON/OFF switch is set to OFF. If the timer is not zeroed (00:00) when
power is turned on, press and hold the CLEAR key on the key pad
control panel until the timer is zeroed.
b. For Dial Tuner Control Panels: Turn the dial counter clockwise until it
points to the 0 mark.
Simultaneous Testing.
Examine the components of th
generator groups simultaneously during Phase 2.
NOTE: The red ON/OFF switch light turns on. The fill valve opens and the
drain valve closes. Water begins to fill the steam generator. After a few
minutes, water appears in the bottom of the float cylinder as the water level
in the steam generator rises.
Test the ON/OFF switch according to component test CT:5.
Four possible malfunctions can prevent water from filling the steam gener-
ator during the preheat and steaming cycle.
• The plumbing between the drain valve and fill valve, or drain valve and
steam generator is blocked.
• The operational water float (upper switch) is malfunctioning.
• The fill solenoid valve is blocked or malfunctioning.
• The 3-way drain valve is blocked or malfunctioning.
1. Check the fill solenoid valve and adjoining plumbing for blockage.
2. Check the drain solenoid valve and adjoining plumbing for blockage.
