Model 34 Electronic LCD Counter
Description
Features
Specifi cations
The Redington Model 34 LCD Totalizer/Preset Counter provides a large display, with 0.28” [7mm] high characters, in industry size housings. The Model
34 counts and displays the number of pulses that appear at its input terminal at a rate of 40 pulses per second (Hz). The input interface handles AC or
DC inputs. The Totalizers are available in 7 different housings. All models are totally sealed and are capable of submersion in 6’ [2 meters] of water. A
wide operating voltage, 10-300VDC and 20-300VAC, makes the model 34 versatile for all indoor and outdoor applications. All models are NEMA 4/4X,
12, & IP66 rated when used with the optional gasket and have a polarized lens which assures high visibility in an outdoor environment.
Maintenance Meters are offered with a maximum of 3 preset “Redi-Alert’s” icons to alert users when service intervals are due or other periodic timed
events are due. Models are available with front panel fi eld or factory programmable alerts. Not only does the display fl ash to get attention, but it displays
a choice of 7 different .08” [2mm] maintenance icons. Models are available with an Open Drain MOSFET output for the actuation of external alarms or
indicator lamps. Users can program or specify the count/service interval and fl ash duration for each Redi-Alert. Flash duration is the amount of time in
hours that the specifi c icon fl ashes before and after the specifi ed total count. If a front panel manual reset of the Redi-Alert is required, the front panel
models with switches must be specifi ed.

Functions
Preset Counter: The preset function is centered on the output signal. When the count reaches the preset value, the output signal is turned “on”. The
Preset function is count “up”. In addition to the preset function, models are also available with 3 Redi-
Alert set points. Upon reaching the preset value the preset can be automatically reset, or it can await an external reset.
Front Panel Switch Functions: Front panel switches can be used for reset, display selection and programming. The two front switches are used
as follows:
SEL: During programming this switch is used to select options and to move horizontally in the programming chart.
RST: This is the reset switch during normal operation. During programming this switch is used to select options and
to move vertically in the programming chart.

Notes
1. When interfacing the Model 34 with a Solid State Relay or AC Sensor, the leakage current needs to be considered. Contact the factory or see the
application note at www.redingtoncounters.com
2. Exceeding the Absolute Voltage Range and the Absolute Maximum Limits may result in damage to the unit.
3. The open-drain MOSFET acts like an open-collector NPN trasistor. Care should be taken since there is no current limiting protection in the unit.
