Wash Wipe Operation
Conditions:
● I NT disconnected.
● C ONT disconnected or connected to ground.
In this condition, the circuit will respond to the switching of W/W to Vbb after a time T1 (see T1 Debounce
Timing). If W/W is disconnected or connected to ground before the end of T1; no action will be taken. After a time T1;
the circuit will perform as shown on Figure 3. The output will turn on and remain on for the duration of W/W. When
W/W becomes inactive, the output will remain on for T2 = 96 x 4 x tb1.
Continuous Operation
In this condition, the circuit responds to the switching of CONT to Vbb. If CONT is connected to Vbb, the output
will turn on regardless of the state of any other input and remain on so long as CONT is active. This command operates
directly on the relay output and does not interfere with any other timing. Therefore, the circuit will not be reset to a
defined state.
Wash Wiper and Intermittent Operation
If W/W is activated during the time INT is also activated, the circuit will respond to W/W after a time T1 (see T1
Debounce Timing). The output will turn on after T1, and stay on for a time T2 + T3 after W/W is deactivated.
Following this, normal operation of INT will occur. This is shown on Figure 4.
