Automatic Reset Manual Reset
Rotate the adjustment control fully clockwise, or until the
red (TRIP) indicator illuminates.
Slowly rotate the adjustment control in a counter clock-
wise direction, just until the green (NORM) indicator
illuminates.
At this point, the Model 2522 is the most sensitive to
irregular power line conditions. If nuisance tripping
occurs, turn the control slightly farther counter-clockwise.
A more accurate setting will require the use of a 3-phase
variac to lower the voltage to an exact measurable setting.
Time Mark offers a factory set versions of all models and
voltage ranges, for only a small additional charge.

TROUBLESHOOTING
Should the Model 2522 fail to operate properly, check that
all three voltages are present and are of the correct
voltage level and phase rotation (a Model 108A or 108B
phase sequence detector may be used to verify phase
rotation). Check all fuses and verify that all wiring
connections are correct. If problems persist, contact your
local Time Mark Distributor, or the manufacturer at 800-
862-2875.
WARRANTY
The Model 2522 3-Phase Monitor is warranted to be free from
defects in materials and workmanship, and is covered by our
exclusive 5-year Unconditional Warranty. If this device fails to
operate, for any reason, we will repair or replace it free, for five
years from the date of purchase. Contact your local Distributor or
the Time Mark Sales department, Monday through Friday; 8 a.m.
to 5 p.m., CST, for further details.
INSTALLATION
Mount the 11-pin socket in a suitable enclosure.
Connect 3-phase power to terminals 5, 6 and 7 on the
socket. Phase rotation may be verified using a Time Mark
Model 108A or 108B Phase Sequence Detector.
Connect the load control wiring to the appropriate
terminals on the socket:
For motor control applications; use terminals 1 and 3.
For phase loss alarm applications; use terminals 11 and 8.
Insert the Model 2522 into the socket and apply power.
If the contacts do not transfer, (green light ON ), check
that all phases are present and of the correct voltage. If
power is correct, rotate the level adjustment counter-
clockwise (CCW). If the contact still does not transfer,
remove power and reverse any two of the three phase
wires at the socket (phase rotation is reversed).
Re-apply power. The contact should transfer to provide a
signal path between pins 1 and 3 and pins 9 and 11. The
green LED should be lit.
NOTE: When installing the Model 2522 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 silicon 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 SETTINGS
The following procedure will allow the Model 2522 to be
adjusted to achieve a trip point just below the nominal
phase-to-phase voltage, where the unit is applied. On
manual reset versions, hold the reset button down
during the following procedure.
