COMPONENT TEST PROCEDURES
The following procedures are detailed tests to determine whether or nor specific
SteamCraft 10 components are operable. Although these tests can be performed
independently, the Initial Test Procedures should be performed to first identify the
most probable causes of trouble. This systematic approach avoids random
unnecessary component testing.
Initial conditions for all testing.
• The right side and from access panel are removed and the float assembly, 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 ON 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 Timer Control Panels: Turn the dial counter clockwise until it points
to the 0 mark.
CT:1. Drain (3-Way) Solenoid Valves
1. Set the voltmeter to the 250 VAC scale.
2
.
Check the drain solenoid ground wire (green) for continuity and secure
connections.
3. Set the ON/OFF switch to the OFF position.
• If water flows from the dram. the drain solenoid is good. End this procedure
here.
• If no water flows from the drain, the fault may not be the drain solenoid.
Check for clogged drain plumbing.
4. Refer to Figures 6-5 and 6-6, and connect the voltmeter leads to test point 1 and
test point 2. With these connections, check for 0 VAC across the drain
solenoid.
• If the meter reads 0 VAC across the drain solenoid, and the drain is draining
water, the valve is operating properly.
5. Refer to Figures 6-5 and 6-6. Connect the ohmmeter leads to test point 1 and
test point 2, and check the resistance across the drain solenoid.
a. If the reading is zero, the coil is snorted, and the solenoid valve should be
replaced.
b. Remove wiring connections from solenoid valve(s) at the terminal strip
before making measurements.
