1.0 WARNINGS, CAUTIONS, AND NOTES
Please read the entire instruction manual before using the voltage monitor.
Also, read the warnings, cautions, and notes in Table 1. Failure to observe the warnings and
cautions can lead to equipment damage or personal injury.
If you have any questions concerning the manufacture, design, function, installation, operation
or maintenance, contact Railway Equipment Company before proceeding.
Table 1. Warnings, Cautions, and Notes
Symbol Description
WARNING indicates a potentially hazardous situation which, if not avoided, could result
in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate personal injury. It may also be used to alert against unsafe practices.
NOTE NOTE indicates explanatory information that applies to the next step in the procedure. It
is used to clarify and expand upon the importance of the procedural step when needed.
If incorrectly wired, monitor can be damaged. Be sure to observe correct polarity on all
DC wire connections, check the AC wiring instructions, and connect the ground wire.

2.0 OPERATION
The model 520603-2V150 voltage monitor is equipped to monitor up to two DC voltage
sources. The unit is powered by the voltage source that it monitors on channel one. The
channel one voltage range is 10 to 48 VDC. Because the unit is powered by the voltage it
monitors on channel one, the display will not illuminate until a voltage source is applied across
pins one (+) and two (-). The unit power usage is a constant 2.5 Watts. The unit is reverse
polarity protected, and the input power is protected by an internal resettable fuse.
Channel two has a voltage range of 1 to 150 VDC, but is only available for use if channel one is
powered. There is 2,500 volts isolation between channels.
The monitor has easy front panel access for set up and wiring. There are form C relay outputs
that are over current protected with replaceable blade type automotive fuses.
To get started, power from the source to be monitored (10 to 48 VDC range) should be applied
across WAGO pins 1(+) and 2(-) using 18 to 14 gauge wire. This provides power to channel
one.
The display idle screen will show voltage. If the applied voltage is between the high and low
voltage parameters, the Channel 1 OK LED will be on, and the channel one relay will be
powered.
2.1 Front Panel Features and Components
This section describes the features and components that are on the front panel of the
voltage monitor (see Figure 1).

2.1.1 Figure 1. Front Panel of Voltage Monitor
2.1.2 Digital Display
The idle screen displays the input voltage. If only channel one has input voltage, only
channel one will be displayed. If both channels are monitoring voltage sources, both
will be displayed. If the optional current or temperature probes are being used, the
lower screen will alternate between displaying channel two voltage, temperature, and
current. With only channel one powered, the following screens will be scrolled through
when the MODE button is depressed:
PASSWORD ___- The password to adjust parameters is 5. It is entered by pressing
the INCREASE button until 5 appears in the parameter field.
MAX VCH1
SET __._ - This displays the high voltage setpoint parameter for channel one. It can
be adjusted from 0 to 50.0 VDC by use of the INCREASE or DECREASE push
buttons. If the input voltage rises above the setpoint, the channel one output relay will
change state and the channel one CHANNEL OK LED will go out. Factory default is
50.0 VDC.
LOW VCH1
SET __._ - Low voltage setpoint for channel one, adjustable from 0 to 50.0 VDC.
If the input voltage falls below the setpoint, the output relay will change state and the
CHANNEL OK LED will go out. Factory default is 0 VDC.
DELAY CH1
SET ___ - Delay time in seconds before a voltage falling outside the parameters
will trigger a fault. This parameter is adjustable from 1 to 600 seconds. Factory
default is 10 seconds.
If a voltage input is added on channel two, in addition to the input on channel one,
the following additional screens to appear as the MODE button is used:
MAX VCH2
SET __._ - High voltage setpoint for channel two. Voltage range is 0 to 150.0 VDC
Factory default is 150.0 VDC.
LOW VCH2
SET __._ - Low voltage setpoint for channel two. Voltage range is 0 to 150.0 VDC.
Factory default is 0 VDC.
DELAY CH2
SET ___ - Delay time in seconds for channel two. Range is 0 to 600 seconds.
Factory default is 10 seconds.
There is an optional amp probe available which can be set up to trip the same relay
as a voltage fault will trip on Channel two. The addition of the current probe will
cause the following additional screens to appear:
