Time Mark 2629 Data Sheet

MODEL 2629

TIME MARK is a division of

AC/DC

Voltage Monitor

 Monitors Over or Under Voltage

 AC or DC from 15 to 260 Volts

 Adjustable Trip Points

 Automatic Reset

 DPDT Relay

DESCRIPTION

The Model 2629 AC/DC Voltage Monitor is designed
to continuously monitor any AC or DC voltage from 15
to 260 volts.

Input voltages above the setpoint cause the output
contacts to energize. Input voltages below the setpoint
cause the output contacts to de-energize. The dead
band between pull-in and drop-out is less than 5%.

Dip switches are used on the Model 2629 to choose
between AC and DC voltage monitoring, and to select
one of the eight trip level ranges. Each trip level has a
user adjustable 35 volt range, with a 5 volt overlap
between the ranges. The unit has a screwdriver
adjustment to set the trip point within that 35 volt range.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 2629.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

INSTALLATION

Connect the voltage to be monitored to the socket using
the Pin Diagram pictured on this data sheet and on the
unit as a reference (contacts are shown in the
de-energized condition).

The output contacts used will depend on whether the
Model 2629 is used to detect over-voltage or under­voltage, and whether the unit will shut off a load, or trip
an alarm.

The monitor’s internal relay will energize when the input

voltage is above the trip level setting. This allows the
unit to be set to detect over-voltage (relay will energize
on fault). The LED indicator will illuminate whenever
the relay is energized.

NOTE: When installing the Model 2629 Voltage Monitor in
areas of high humidity or contamination, it is recommended that
the base area and all exposed metal parts of the socket be coated
liberally with a good quality silicone grease, such as Dow Corning
DC-4 or DC-4X. Insert the unit into the socket and wipe off
excess grease around the base. This will prevent the entrance of
moisture and other contaminates into the base and socket areas.

ADJUSTMENT PROCEDURE

Select the range where the desired trip voltage falls in
between the choices shown on the chart shown below. The
same Range Chart is also screened on the unit.

Set the dial to the difference between the desired voltage and
the low number selected.

TROUBLESHOOTING

Should the Model 2629 AC/DC Voltage Monitor fail to operate,
check all connections. Verify that the proper voltage is
present, and check all fuses. Should problems persist,
contact the factory at 800-862-2875, for assistance (Monday
thru Friday, 8 a.m. to 5 p.m. CST).
