Surge Guard Automatic Transfer Switch Remote LCD
Display Operation (Model: 40299)
This article provides basic operation instructions for a Surge Guard Automatic Transfer Switch Remote LCD Display
(Model: 40299).
The optional Remote LCD Display is intended for use
with Automatic Transfer Switch (ATS) unit 40350-RVC or
41390-RVC.
The Remote Power Control allows you to see detailed
information such as voltages for Line 1 and Line 2,
(typically 110-120VAC), current draws (0 to 50Amps),
and status and conditions of the ATS, including time
and date. Electrical faults, such as low voltage or an
open ground connection, that cause the ATS to shut off
power are shown on the remote display, allowing you to
retrieve via the joystick a log of fault conditions kept by
the ATS of electrical power at your location.
This is a helpful diagnostic tool that allows you to
comprehend and correct problems with your RV’s power.
The display also features a right/left navigation lever
allowing navigation through the various screens.
Features and Displayed
Information
MAIN SCREEN
•
Display of normal operating voltages and currents,
for example 120V 25Amps for each Line (240V
system). Shore power or generator power.
•
Display of faulty power conditions responded
to by ATS such as low voltages, high voltages,
open ground, open neutral, reverse polarity, high
frequency, etc.
•
Display of delay condition when recovering from
faulty conditions.
L1/L2 VOLT AND CURRENT SCREENS
Displays line 1/2 voltage or current. This is handy as it
allows you to view the voltage or current when there is a
fault condition being displayed on the main screen.
FAULTS SCREEN
Allows you to view a history of up to 50 faults which
have been logged by the ATS. Each fault that has been
logged contains the fault, the voltages and currents
at the time of the fault, and the time and date when it
occurred.
TIME/DATE SCREEN
Displays the current time and date and allows you to set
the current time and date on the ATS unit.
JOYSTICK LEVER
To navigate through screens and set the time and date.
Operating Instructions
SCREEN NAVIGATION USING THE
BUTTON/LEVER
There are several information screens associated with the
Remote Display which can be selected via the lever on the
front of the unit. Pushing the lever to the RIGHT repeatedly
will access the screens in the following order. Pushing
the lever to the LEFT accesses the screens in the reverse
order.
When the VIEW FAULTS screen is displayed, momentarily
pushing the lever in accesses a log of faults which have
been stored by the ATS unit. Viewing the fault log data will
be explained in more detail below.
DISPLAY FOR NORMAL OPERATION
During normal operation, the Remote Display screen reads
the status of the RV electrical power, showing continuous
voltages and currents for power lines 1 and 2 coming into
the RV on the main screen. A secondary screen showing
SHORE or GEN will momentarily display approximately
every 8 seconds, indicating whether your RV is running on
power for your shore connection or whether the ATS has
transferred you over to generator power.
DISPLAY DURING FAULT CONDITIONS
If there are any faults or problems with your electrical
power, the Remote Display will show the particular faults
on the LCD screen with a 3 second interval between each
item. The faults displayed can be any combination of the
ATS fault codes.
