parameters that are visible in SiteTech. Parameters
marked Read Only are not user-adjustable.

column, and the line in the table is shaded gray.
Parameters that apply to an optional Model RXT
transfer switch, programmable interface module (PIM),
or load management device (LCM, load shed kit, or RXT
combined interface/load management board) are noted
in the last column.
The table indicates the following:

4.4.2 Notes on Selected Parameters
Temperature Settings
In SiteTech, all temperature settings are shown in
degrees F but stored as degrees C. When you highlight
a parameter value (click it), the _F value changes to the
equivalent _C value. Enter temperature settings in _F.
The new setting is calculated from a conversion
equation, so the final value may include some rounding
that makes the setting higher or lower by 1 degree.
Engine Speed Governor Settings
Engine Speed Adjustment. The default setting for the
engine speed adjustment is 50. This gives engine
speeds of 3600 RPM for 60 Hz models, and 3000 RPM
for 50 Hz models. See Section 6.9.2 for instructions to
adjust the engine speed, if necessary.
Note: The system frequency must be set correctly
before adjusting the engine speed setting.
Engine Speed Gain Adjustment. The recommended
setting for the engine speed gain adjustment is 50,
which is the default setting. See Section 6.9.1 for
instructions to adjust the Engine Speed Gain, if
necessary.
Genset Info
Model numbers and serial numbers are factory-set for
each unit. If the controller is replaced, the genset model
number and serial number will need to be entered by the
installer. For the genset model number, select the
appropriate model from the dropdown list. Find the
generator set serial number on the nameplate and enter
it using SiteTech. See Section 4.6, Controller
Replacement, for information about other setup
required on a replacement controller.
Changing the genset model number will update the
engine model number automatically. Select the genset
model number and then click Apply Changes in SiteTech
to see the updated engine model number.
Genset Fuel Type
The Genset Fuel Type setting is located in the Genset
System Configuration group in SiteTech. Generator set
power and current ratings are different for different fuel
types (natural gas or LP). The fuel type setting is
available in SiteTech with controller firmware versions
4.5 and higher.
Changing the Genset Fuel Type setting automatically
updates the the Genset Power Rating and Genset
Rated Current settings. The power rating is used to
determine setpoints for the optional load management
device. If load management device is connected and
the generator set is converted to a different fuel, use
SiteTech to change the Genset Fuel Type setting.
Digital Inputs and Outputs
Digital inputs and outputs are available only if the
optional Programmable Interface Module (PIM) is
connected to the RDC2 controller. One PIM provides
two digital inputs and 6 digital outputs.
Dropdown menus allow selection of the digital input and
output events. Be sure to select Digital Inputs B1--B2
and Digital Outputs B1--B6 in SiteTech. Digital Inputs
A1--A2 and Digital Outputs A1--A2 do not apply to the
PIM. Digital outputs B7-- B12 are reserved for load
