MOUNTING
Mount the 99B-MI in an accessible location using suitable
hardware per installation (#10 Screws recommended)
BEFORE MAKING CONNECTIONS !
Shut off power to all circuits before making any electrical
connections. DO NOT connect 115VAC mains power to 99B-MI
until all other wiring connections have been made
All clocks should be installed / mounted with all clock hands
pointing at 12:00. Clocks will automatically reset to correct time
when power is applied to 99B-MI
For ease of installation, all 99B-MI Inputs & Outputs are shown
on the wiring label on the inside of the terminal compartment
cover. (See Pg. 5)
CONNECTING “MI CLOCKS”

TROUBLESHOOTING
Under certain conditions, when the 99B-MI is automatically correcting the clock hands
(i.e. “Reset Mode”), the hands may not move for up to 2 hours. This is NORMAL. To
determine if there is a actually a problem with your 99B-MI or your clocks, see below.
CAUTION: ONLY A QUALIFIED ELECTRICIAN SHOULD PERFORM ANY
TROUBLESHOOTING RELATED TO ELECTRICAL WIRING
1) Is the 99BMI live?
!If the LCD Display is working and the green “ON” LED is blinking, the 99BMI is live
YES: Goto Step 2
NO: Check 115VAC input power and both fuses in wiring compartment
2) Is the green LED marked “ON” in the 99BMI Front Panel blinking?
YES: Goto Step 3
NO: Contact Electric Time Company Service Department
3) Is the 99B-MI providing power to the clocks?
!Open the wiring compartment cover (unscrew the two hold-down screws)
!Is the 2.5A secondary fuse blown?
YES: Replace fuse. See “My Clocks are not on time” Pg. 15 to reset clocks as
required
NO: Goto Step 5

TROUBLESHOOTING
4) Is the 99B-MI in “Reset Mode”?
!When in “Reset Mode” the 99B-MI display will alternate every few seconds
between the “Running” display (See Pg. 10) and the “Correcting Clock” display
(See Pg. 10)
Is the 99B-MI alternating between the “Running” and “Correcting Clock” displays?
YES: Goto Step 6
NO: Goto Step 7
5) Does the 99B-MI know where the clock hands are?
!The “Correcting Clock” display will show where the 99B-MI thinks that the clock
hands are currently located (example: “Hands At: 12:00”)
Does the “Correcting Clock, Hands At:” display match the current hand position?
YES: Hands will begin moving at correct time within the next 2 hours
NO: See “My clocks are not on time” Pg. 15, Step 3
6) Check wiring
!Verify all wiring is OK from 99B-MI to each clock Note: this is one of the most
common errors when installing the clock controller, be sure to check the wiring at
the clock movement and clock control.
Is wiring OK?
YES: Possible failure of motor or circuit board on clock (CMI PC Board)
Contact Electric Time Company Service Department
NO: Fix wiring, repeat troubleshooting as required

DST Change (North America only)
Beginning in the Spring of 2007, the Energy Policy Act of 2005 changed the starting
and ending dates of Daylight Saving Time for the United States. As of January 1st
2006 all controls shipped from Electric Time Co. have the updated Daylight Saving
Time for 2007 and beyond.
In the event the US Government reverts to the 2005 Schedule or a different DST
schedule the 99B-MI clock controller is capable of being reprogrammed with a new
DST rule through the user interface. For more details on changing the DST rule
please see page 13.
