Testing the Solid State Percent Timer
The percent timer should be tested for proper operation at the beginning of each growing season and then every
month throughout the season.
To test the percent timer do the following:
1. Set the percent timer to 20% on the dial. See Figure 31-1.
2. Start the machine.
3. Watch the End Tower indicator light for several complete cycles (ON/OFF) of the timer to insure you catch
a complete timer cycle. See Figure 31-1.
• 60 second cycle timer, the End tower light should be ON for 12 seconds and OFF for 48 seconds. If the
End Tower indicator light is ON for more than 13 seconds or less than 11 seconds the percent timer is not
operating properly and must be replaced.
• 120 second cycle timer, the End tower light should be ON for 24 seconds and OFF for 96 seconds. If the
End Tower indicator light is ON for more than 26 seconds or less than 22 seconds the percent timer is not
operating properly and must be replaced.
• If the End Tower indicator light is ON or OFF continuously the percent timer is not operating properly and
must be replaced.
