Time Mark 16-1-X-X Data Sheet

MODEL 16-1-X-X

TIME MARK is a division of

Over / Under Voltage Monitor

with Trip and Restart Delay

⚫ Monitors AC or DC single phase voltages
for over, under or over/under voltage

⚫ Adjustable Trip & Restart, can be disabled
⚫ 5 LEDs: Trip, Normal & Delay status
⚫ Universal range: 12–30 or 30–277 VAC/VDC
⚫ 8-pin plug-in case - 2 SPDT relays

Surface/DIN rail mount - 1 SPDT relay

DESCRIPTION

The Model 16-1-X-X protects equipment from Over,

Under, Over/Under voltage or rapid cycling conditions
that can damage valuable equipment. Trip and restart
delays are adjustable, or can be disabled. Input voltage

ranges are 12-30 VAC/VDC or 30-277 VAC/VDC. The 8

-pin plug-in has 2 SPDT relays, while the surface/DIN

Rail mount case has 1 SPDT relay. See Ordering

Information for details. 8-pin plug-in versions require an
8-pin socket, such as Time Mark's Model 51X120.

A proprietary microcontroller-based sensing circuit de-

energizes the relay(s) after the trip delay (if enabled) upon
detection of harmful voltage conditions. The relay(s) will
energize after power line conditions return to an
acceptable level and the restart delay time has expired (if

enabled). Trip delays can be added to avoid nuisance

tripping while restart delays can be used to stagger the
startup of equipment or protect compressors. Time

Mark’s proprietary microcontroller-based design offers
maximum flexibility with an easy to use interface.

MODEL 16-1-X-X

TIME MARK is a division of

Over/Under Voltage Monitor

with Trip and Restart Delay

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

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 16.

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

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

DIMENSIONS - Surface/DIN Rail Mount

INSTALLATION AND ADJUSTMENT

Begin with NO POWER APPLIED to the unit, making

adjustments with a non-conductive tool being careful not
to apply excessive torque to the controls.

Adjust the HIGH SETPOINT control fully clockwise (right
toward +), adjust the LOW SETPOINT control fully

counter-clockwise (left toward -).

Adjust the TRIP DELAY fully clockwise (right toward +

for max) and RESTART DELAY fully counter-clockwise
(left toward - for disabled).

8-Pin Case: Connect the voltage to be monitored to the
socket using the pin diagram on the unit OR

Surface/DIN Rail Mount Case: Attach 1/4” terminal
lugs to the input voltage wires, and connect to the

terminals marked INPUT (refer to diagram on unit).

Apply power to the unit. The LED lights will sequence on
during self test. Complete the setup procedure in the
following box for either an Over Voltage, Under
Voltage or Over/Under Voltage monitor depending on

how you wish to configure your Model 16-1.

INSTALLATION AND ADJUSTMENT (cont’d.)

Over voltage with trip and restart delay

Slowly rotate the HIGH SETPOINT control counter­clockwise (left toward -), until the UPPER TRIP LED

illuminates, and the TRIP DELAY LED blinks. Adjust
HIGH SETPOINT control clockwise (right toward +) until
the DEVICE NORMAL LED illuminates and the TRIP

DELAY LED stops blinking.

Under voltage with trip and restart delay

Slowly rotate the LOW SETPOINT control clockwise
(right toward +), until the LOWER TRIP LED illuminates,
and the TRIP DELAY LED blinks. Adjust LOW

SETPOINT counter-clockwise (left toward -) until the

DEVICE NORMAL LED illuminates and the TRIP

DELAY LED stops blinking.

Over/Under voltage with trip and restart delay

Follow the instructions above for Over voltage with trip
and restart delay and Under voltage with trip and

restart delay to enable both ranges.

Adjust the TRIP DELAY and RESTART DELAY time to
the desired setting. A TRIP DELAY or RESTART
DELAY is optional, and can be disabled by turning the

control fully counter-clockwise (left toward -) if desired.

Specific setpoints will require the use of an adjustable
voltage source such as a VARIAC and a voltmeter.
Note: TRIAC type light dimmers do not provide a full
sine wave and will not provide a reliable calibration

voltage.
