R-panel Technical Manual

ACTIVE ALARM

Low Oil Pressure, High Coolant Temp, Low Coolant 
Level, Overspeed, Overcrank, Engine Speed Signal 
Loss and a Dead Battery indication will all be latched 
shutdowns. In the event one of these conditions 
occurs, the unit will be shut down, the appropriate 
LED will be illuminated, the alarm relay output will 
be activated and the unit will not start again without 
manual intervention (see Re-Crank below).

RE-CRANK

If an engine speed signal failure occurs while the gen-
erator is running the engine will shutdown and then 
attempt a re-crank. A maximum of two re-cranks will 
be attempted after which the overcrank LED will be 
set. If the engine speed signal failure occurred during 
the engine exercise mode the exercise timer will con-
tinue from where it was at the start of the re-crank 
and is not reset.

NORMAL EXERCISE MODE

To select this mode, place DIP switch position 3 in 
the ON position.

In Normal Exercise Mode the 2.4L and 3.0L genera-
tors will exercise at 3600rpm.

The R-200 controller will start and run the generator 
once every seven (7) days for approximately 12 min-
utes. If the utility fails during the exercise period, this 
exercise period is aborted and the R-200 Controller 
transfers the load to the generator output, assumes 
automatic operation and continues to run until the 
utility is returned.

The weekly exercise cycle is set as follows:

1.  Place the AUTO/OFF/MANUAL switch in the 

AUTO position.

2.  Press and hold the "Set Exercise Time " switch for 

five (5) seconds and then release.

At this time all five (5) red LED's will flash for 10 
seconds, then the engine will start and run for it's 
12 minute exercise period, then shut down. The gen-
erator will now start and run each week at approxi-
mately the same time.

If battery power to the R-200 Controller is lost, the 
weekly exercise time setting will be lost. This is indi-
cated by all five (5) red LED's continually flashing in 
ATS mode. In this state the generator will still start 
and run in MANUAL mode, or automatically start 
and run if utility voltage is lost while in AUTO mode, 
but it will NOT perform a weekly exercise cycle.

In the event of a failure while running in this mode, 
the five (5) red LED's will stop flashing, the indi-
vidual fault LED will turn on and the engine will be 
shut down. Once the AUTO/OFF/MANUAL switch is 
switched to OFF, the individual fault LED will turn off 
and the five (5) red LED's will begin flashing to show 
that the exercise mode has not yet been set.

LOW SPEED EXERCISE

To select this mode place DIP switch position 3 in the 
OFF position.

In Low Speed Exercise mode the 2.4L and 3.0L gen-
erators will exercise at 1800 rpm.

If the utility fails during the low speed exercise period, 
a 10 second timer will start. If the utility returns to 
a normal operating level, during this 10 second time 
interval the low speed exercise operation will contin-
ue. If the utility is still not present (i.e. utility voltage 
less than 60% of nominal) when the above 10 second 
timer expires then the low speed exercise mode is 
terminated and the engine will ramp up to its normal 
running speed within five (5) seconds. If the utility 
returns during the five (5) second ramp-up period 
the generator will terminate the exercise mode. If the 
utility is still not present, once the generator is up 
to its normal running speed, then the controller will 
transfer the load to the generator. When the utility 
returns the generator will shutdown.

If battery power to the R-200 Controller is lost, the 
weekly exercise time setting will be lost. This is indi-
cated by all 5 red LED's continually flashing in ATS 
mode. In this state the generator will still start and 
run in MANUAL mode, or automatically start and run 
if utility voltage is lost while in AUTO mode, but it 
will NOT perform a weekly exercise cycle.

In the event of a failure while running in this mode, 
the five (5) red LED's will stop flashing, the indi-
vidual fault LED will turn on and the engine will be 
shut down. Once the AUTO/OFF/MANUAL switch is 
switched to OFF, the individual fault LED will turn off 
and the five (5) red LED's will begin flashing to show 
that the exercise mode has not yet been set.

AUTO START

This unit is designed to automatically start in the 
event of a utility failure. A utility failure is defined as 
the utility voltage being less than approximately 60% 
of nominal, while the utility is considered good when 
it is restored to approximately 80% of its nominal 
value.

If the generator is already running under exercise 
when an auto start is required, it will simply transfer 
the load after a 15 second delay and then switch to 
auto operation.
