QUESTIONS ABOUT THE OPTIONAL BATTERY PACK
***
04-1
I added a battery pack for power failure protection. Is there anything else I have to do besides plug It Into CN3?
A4-1
You should set the PF parameter in the configuration to either OP if you want power fail open, or CL if you want power
fail close.
Q4-2
My door is stuck open, and the display is flashing bF.
A4-2
You have a self-monitoring style battery pack, and the batteries may be defective; or, if the pack was just installed, the
batteries may need to be charged. The orange 'FAIL' LED on the battery pack will also be lit when bF shows. Push the FAIL
RESET button

to attempt to clear the condition. The FAIL indicator may or may not go out. If it
goes out, do a manual battery test as explained below to determine whether the failure was due to a remotely possible 'glitch' or
is really indicating a battery failure. If necessary, replace the batteries or the complete assembly.
Q4-3
Do the batteries continue to drain after the door completes its cycle on power failure?
A4-3
No.
04-4
Can the batteries be tested manually?
A4-4
Yes. If you have the unmonitored version of the pack circuitry, simply unplug power to the control, or turn off the
breaker supplying power to the door. The display should switch to PF within 1 second, and the door should open or close,
depending on whether the PF option bit is set to OP or CL. After the door arrives at the proper position, the entire control should
go dead until power is restored. When power is restored, the red CHARGE indicator on the pack circuit board will glow for 4-6
minutes, then will dim and go out completely (this assumes that the batteries were fully charged when you performed the test).
if
you have the self-monitoring version of the pack circuitry, press
and hold the TEST button on the pack circuit board until the
yellow TEST indicator comes on, then release it. The pack is now self-testing to insure that enough battery power is present to
open or close the door for one cycle. If all is well, the TEST indicator will go out after about 15 seconds, and the red CHARGE
indicator will come on. It will glow for 5-7 minutes, then will dim and go out completely (this assumes that the batteries were fully
charged when you performed the test).
04-5
How often is the battery pack tested?
A4-5
In the self-monitoring pack, the batteries are tested immediately upon power-up and at least once every hour thereafter.
Q4-6
Which battery pack, self-monitored or standard, does Horton recommend?
A4-6
We strongly recommend that you stick with the standard version of battery pack unless there is a compelling reason not
to. There are a variety of reasons as follows:
1. U.S. door operators typically use mechanical protection (e.g. breakouts) as the primary means for safety-to-life concerns -
the battery pack operation is secondary.
2. ANSI standards for automatic doors in the U.S. do NOT require periodic testing of battery packs.
3. The battery manufacturers have stated that regular periodic testing is not only unnecessary, but it actually shortens the life
expectancy of the batteries.
4. Eliminating the self-test circuitry reduces complexity (and hence, price). Finally, reliability is also enhanced, since there are
fewer components.
04-7
What happens if the pack test falls?
A4-7
A battery failure will move the door to the full open position. The door will stay open and the display will flash bF until
the failure is corrected.

MISCELLANEOUS QUESTIONS

Q5-1
I arrived at the jobsite for troubleshooting, and the C2150 is flashing nS. The switch seems OK, and the yellow
close monitor LED lights when the switch is tripped. What else could be wrong?
A5-1
Anytime that nS flashes, the door is not arriving at the fully closed position. Check for a mechanical jam at some point
In door closing. Also, this will normally never happen if the reversing sensitivity is adjusted properly - the door will recycle
Instead when the obstruction is encountered. Find and correct the cause of the obstruction, then check the reversing sensitivity.
Q5-2
When the door starts opening, it slows down almost immediately, then slowly Increases speed and eventually
shuts off. The display flashes EF momentarily. Why?
A5-2
This display means 'Encoder Failure.' The position encoder is not connected, or is defective. Check your encoder
wiring and run the quick encoder test.
05-3
When I try to store values, my control starts blinking dF and quits working until reset.
A5-3
The control has failed and must be replaced.
05-4
When I power up the control, the door refuses to move at all, but the display Indicates that something Is trying
to happen. What do I check first?
A5-4
If the door will not move at all, first check fuse F2 on the power supply. This fuse protects the high-voltage (motor)
power supply. If F2 is blown, replace it with a slow-blow 3.15A 5x20mm fuse (T3.15A) - Buss type GDC3.15, or equal. Caution,
disconnect power and wait 30 seconds before servicing the power supply assembly!! If F2 seems to be OK, check the motor
and motor harness for an open motor. Finally, if both the motor and F2 appear to be good, replace the C2150 control.
NOTE: If fuse F2 continues to blow at totally random intervals, there is a good possibility that the door is being locked manually without
turning off the toggle circuitfirst. If Version 3.02 or earlier is installed, upgrading to a laterversion will normally circumvent this problem
with the new jam sensing feature. See question 5-15 for more details.
