VII. Operating Instructions
NOTE: The Extender cannot be operated with water pressure above 10 PSI.
The Extender is the perfect accessory for monitors used on pumpers where the monitor
needs to clear an obstruction. The Extender is a continuous motion elevator that once
engaged will travel the full distance (18”) either up or down, without user intervention.
A. Press the “UP” button on the controller when the Extender is in the fully retracted (down)
position.
1. The unit will fully extend without the operator having to hold the button down.
2. Once the unit starts moving the yellow LED will illuminate and the green LED will
blink at a moderate rate.
3. Once the elevator is fully extended the yellow LED will extinguish and the green LED
will remain on indicating a fully extended (up) condition.
4. If, during upward travel, the operator pushes the “DOWN” button, the Extender will
immediately stop, pause for approximately one second, and start back down.
a. The yellow LED will remain on.
b. The green LED will extinguish and the red LED will start blinking once the unit
starts moving.
c. At the end of downward travel, the yellow LED will extinguish and the red LED
will remain on indicating a fully retracted (down) position.
B. Press the “DOWN” button on the controller when the Extender is in the fully extended
(up) position.
1. The unit will fully retract.
2. Once the unit starts moving, the yellow LED will illuminate and the red LED will blink
at a moderate rate.
3. Once the Extender is fully retracted, (down) the yellow LED will extinguish and the
red LED will remain on indicating a fully retracted (down) condition.
4. If, during downward travel, the operator pushes the “UP” button, the Extender will
immediately stop, pause for approximately one second, and start back up.
a. The yellow LED will remain on.
b. The red LED will extinguish and the green LED will start blinking once the unit
starts moving.
c. At the end of travel, the yellow LED will extinguish and the green LED will
remain on indicating the unit is in the fully extended (up) position.
Whenever the Extender is NOT fully retracted (down), a ground is switched on so that an
optional position warning indicator, provided by the OEM, will come on. The ground is capable
of sinking 200mA of current, which is sufficient to drive an LED or relay coil. The ground is only
available when the unit is NOT in the fully retracted position, in the fully retracted (down)
position the ground is switched off.
