WIRING RECOMMENDATIONS
Following these suggestions will increase noise immunity
and lengthen unit life.
Cable: The connection between the count source and the
ratemeter should be made with a two-conductor shielded
cable. The shield should be connected to earth ground at
one end only. The connecting cable should not be run in
conduits with cables switching high inductive loads.
Relay Coil Suppression: If a relay contact is used as a
count source, the relay coil should be suppressed. This
can be accomplished with an RC network for AC coils or a
diode for DC coils. The Durant RC suppressor (38091-
400) may be used.
Mounting: The totalizer should not be mounted near a
solenoid or other inductive devices. Enough ventilation
should be supplied to keep the ratemeter operating within
the temperature specifications. Do not mount this unit in a
heavy vibration area.
BATTERY SAFETY
The lithium battery that powers your device contains in-
flammable materials such as lithium organic solvent, and
other chemical ingredients. Explosion or fire may result if
the battery is not handled correctly. To avoid an accident
follow these guidelines:
*
Do not heat batteries above 95°C
*
Do not recharge lithium batteries
*
Do not dispose of batteries in fire
*
Insert battery with correct polarity
