TIME MARK is a division of
Frequency Monitor
User selectable relay operation
options
Low or High Trip with independent
delays or disabled
User programmable
Can be restored to factory settings
Model 27SG has silver with gold
flash contacts for low current.
DESCRIPTION
Model 29 Frequency Monitor has a display that shows
the frequency with an accuracy of +/- 0.5%. The display
is updated every second and re-initialized every 30
seconds.
Model 29 has a rotary encoder with switch on the unit.
By pressing the encoder switch for more than 5
seconds, the unit will enter the setup mode.
This unit has a user selectable relay option for High-Low
or DPDT. It can also be user-selected to energize on
fault or de-energize on fault. The user can select
automatic or manual restart on the Model 29. The SG
version of the Model 29 has silver with gold flash
contacts for low current applications
Model 29 Frequency Monitor can be restored to
factory defaults.

Installation Instructions
INSTALLATION AND SETUP
Controls:
Rotary encoder with switch. Pressing the
encoder switch will display the set points.
Pressing the encoder switch for more than 5
seconds will enter the setup mode. Pressing
switch displays the next menu item. Holding
down the switch during setup mode will sequence
through menus with 1 second intervals. Rotating
the knob clockwise increases the value and
counter-clockwise will decrease value.
For non-value options, rotating the knob either
way will change the options on the display.
Setup Options:
(Press encoder for at least 5 seconds to enter
setup)
Frequency range select—*Default 50/60Hz
50/60Hz
400Hz
*Note: For 400Hz—Check Jumper under top left
terminal cover.
High frequency: ( Factory Enabled, Set point =
70Hz, Delay =5S)
Enable/Disable: (If disabled set point and delay
are skipped)
Set point Range:
Low Set +1% to 600Hz in 0.5Hz steps
High trip delay:
0 to 20.0 seconds in 0.1Sec steps
Low frequency: ( Factory Enabled, Set point =
40Hz, Delay = 5S)
Enable/Disable (If disabled set point and delay
are skipped)
Set Range:
40 to High Set -1% in 0.5Hz steps
Low trip delay:
0 to 20.0 seconds in 0.1Sec steps

(To allow for solid lock)
Restart from setup:
Automatic Restart Delay setting
Restart from loss of lock:
5 Seconds Minimum or Automatic Restart Delay setting
(To allow for solid lock)
Factory settings can be restored in field.
To enter calibration:
Press encoder while applying the DC voltage. Release
encoder when TIMEMARK appears.
Restore factory settings: (Default = No)
No
YES
Press encoder after making selection.
UNIT FIELD RESTORE FACTORY SETTINGS
1) From a powered down condition. Apply the AC voltage
first.
2) Press and hold the Encoder switch while applying the
DC power to the unit. As soon as the splash screen
appears release the button. The display will show “No
Rest Fac”. Rotate encoder to change option to “Yes” to
restore factory settings. Press the Encoder switch.
3) The unit will return to normal operation.
