STEP 10 – Test and Adjustment (Figure 13)
(Also see “Sensor Features” on Page 7.)
Zurn Automatic Sensors are preset at the factory and provide
the user with selectable options as follows:
Switch 1 – Automatic Flush (Factory setting is on.)
Switch 2 – Red/Green LED (Factory setting is on.)
Switch 3 – Courtesy Flush (Factory setting is on.)
• Red/Green LED –
With power applied the red light will
illuminate when an object is detected. The green light will
illuminate after the object has been detected for a minimum
of 8 seconds then leaves. The green light indicates the
flushing sequence.
• Range Adjustments –
The Zurn Automatic Sensors are
factory set to operate at a range of 50". This range should
be satisfactory for most installations. If the range is too short
(i.e., not detecting the user) or too long, adjust the range.
•
To Make A Range Adjustment –
Remove the rubber push
caps. The range adjust ment is shown in Figure 13. Using a
small screwdriver, turn the range adjustment clockwise to
increase range (maximum range is 60") or counterclockwise
to decrease range (minmum range is 12").
CAUTION:
Range adjustment rotates only 1/2 turn total from
min. to max. Do not exceed this or sensor will be damaged.
Stand in front of the Zurn Automatic Sensor at the desired distance;
the red light will illuminate when you are within range.
Repeat adjustment procedure until the desired range is obtained.
• Switch Settings
(Figure 13)
The three switches control the following options. They can be
activated or deactivated by means of the switches (down is
on, up is off).
Switch 1 – Automatic Flush –
The unit will auto matically
flush 24 hours after last user.
Switch 2 – Red/Green LED –
When an object is detected
the Red LED illuminates. The Green LED illuminates while
flushing.
Switch 3 – Courtesy Flush –
When an object has been
detected for two seconds, the unit flushes and goes into the
normal mode. This is repeatable after 90 seconds.
NOTE:
After the options have been selected the reset button
must
be pushed for sensor to accept selections. Make sure
rubber push caps are securely installed after making adjust-
ments to protect sensor from moisture.
STEP 11 – Adjust Control Stop
(Figures 6 and 12)
Adjust the control stop to meet the flow rate required for proper
cleaning of the fixture. Open control stop counter clockwise one-
half turn from closed position. Activate Flushometer simulating a
user. Adjust the control stop after each flush until the rate of
flow delivered properly cleanses the fixture.
