3-Second Timer And Buzzer (Mechanical Timer Units Only) - Cleveland steamcraft 21-CET-8 Service Manual

3-Second Timer and Buzzer (mechanical timer units only)

• If the float assembly performs as described above, it is operating properly.
End this procedure here.
• If the upper float does not cycle with the water level, it is jammed or
damaged. Clean or replace the float assembly.
• If the water level in the cylinder continues to rise after the upper float reaches
the upper stop, continue this procedure with step 11.
11. Measure the voltage across the fill solenoid valve terminals.
• If the meter reads 120 VAC, the high level float switch is faulty. Replace the
float assembly.
• If the meter reads 0 VAC, the fault is not in the float assembly. Test the fill
solenoid valve.
1. Set the voltmeter to the 250 VAC scale.
2. Set the ON/OFF switch to the ON position.
3. Set the TIMED/MANUAL switch to the MANUAL position.
4. Refer to Figure 5-28, and connect the voltmeter leads across timer terminals 1.3
(LOAD).
5. Set the TIMED/MANUAL switch to TIMED, and check for 120 VAC across timer
terminals 1-3 (LOAD).
• If the meter reads 120 VAC across the test points, continue this procedure
with step 7.
• If the meter does not read 120 VAC across the test points, continue this
procedure with step 6.
6. Refer to Figure 5-28, and connect the voltmeter leads across timer terminals 2-3
(INPUT). Check for 120 VAC across the test points.
• If the meter reads 120 VAC across the test points, replace the 3-second timer.
• If the meter does not read 120 VAC across the test points, check the
white/black wire from the 3-second timer to relay K1, and the pink wire from
the 3-second timer to the dial timer for continuity and secure connections.
Replace or repair faulty wiring and connections.
7. Check the meter readings and buzzer as the 3-second timer counts down.
• If after 3 seconds, the 120 VAC meter reading drops to 0 VAC and the buzzer
stops sounding, the 3 -second timer and buzzer are working properly. End
this procedure here.
• If the voltmeter reading remains at 120 VAC and the buzzer continues to
sound for more than 3 seconds, replace the 3 -second timer.
• If after 3 seconds, the 120 VAC meter reading drops to 0 VAC but the buzzer
does not sound, either the buzzer wiring or the buzzer are faulty.
