3.
Flow rate display — The standard display is a 3½ digit LED. The left digit shows only 0 or 1.
4.
Totalizer — The standard totalizer is a 7 digit LED. It has a built-in lithium battery with an
8 year life for power off count retention. A reset button is located inside the enclosure, on the
totalizer printed wiring board. Additionally, the totalizer may be reset without opening the
enclosure through the use of a small magnet; a magnet is provided with the unit, and is located
on the inside surface of the enclosure door. To utilize this method, the magnet should be
placed on the outside of the enclosure after installation of the unit. Simply bring the magnet
close to the totalizer window, to the spot labeled "TOTALIZER RESET;" this action will reset
the totalizer.
Installation note: To preserve its life during storage, the totalizer battery is shipped in the
"off" position. It must be turned "on" in order to properly retain its count when power to the
unit is disconnected. To turn the battery "on," go to the display board mounted in the
enclosure window. The shunt header is located near the battery (see drawing). Move the
shunt from the "off" position (left and center pins) to the "on" position (center and right pins).
If the unit is ever put into long term storage, the shunt should be returned to the "off" position
to preserve battery life.

Flow switch relay — Flow switches may initially indicate a high flow rate even for zero flow
when power is first applied to the unit. Correct indication of flow will result after an initial
period which can extend to forty seconds depending on where the trip value is set. The relay
in standard flow switches is picked up (energized) when the flow rate is above a set point. A
loss of flow is therefore indicated in the event of loss of power to the sensor when connected
to N.C. contacts. If the switch option has been ordered for high flow indication, the relay will
be energized with flow below the trip value. See CUSTOM INFORMATION, SECTION 6
for details on operation of the relay.
