When CYCLE-SENTRY Mode is selected, the unit will start and stop automatically to maintain
setpoint, keep the engine warm, and the battery charged. When Continuous Mode is selected,
the unit starts automatically and runs continuously to maintain setpoint and provide constant
airflow.

e:: The SR-3 Controller provides a wide range of control and programming flexibility.
However, pre-programming of the unit controller may prohibit operation in certain
temperature ranges within some modes and may also prohibit certain modes of operation.
In CYCLE-SENTRY, if the block temperature falls below -1 C (30 F), the engine will start and run
until the block temperature is above 32 C (90 F). If the battery voltage falls to the programmed
limit selected by CYCLE-SENTRY Battery Voltage (typically 12.6 volts) and Diesel CYCLE-SENTRY
mode is selected, the engine will start and run until the charge rate falls below that programmed
by CYCLE-SENTRY Amps (typically 2 amperes).
Features of the CYCLE-SENTRY system are:
•
Offers either CYCLE-SENTRY or Continuous Run operation.
•
Controller regulated all season temperature control.
•
Maintains minimum engine temperature in low ambient conditions.
•
Battery Sentry keeps batteries fully charged during unit operation.
•
Variable preheat time.
•
Preheat indicator buzzer.
Data Logging
There are two separate data loggers. The data is downloaded through one of the data ports using
a flash drive or a PC and WinTrac software.
