7.8 Fitting Power
FITTING POWER ISSUE
My DC unit scans as AC.
My AC unit scans as DC.
My SSPS unit scans as DC.
My SSPS unit scans as AS.
When I scan the fitting, I don't see real fitting numbers. I get
some crazy S/N and model information like:
S/N:100001
Model:181.535.21.1
Sometimes when I scan my fitting, the fitting locks up.
I am used to seeing continuous red light from my fitting
when power is really low (dead), but I don't see that
anymore.
After I RESET my fitting (ex: pulling and replacing shut off
screw, remove and add power, manual or Commander
RESET), the fitting acts as if power is dead. Scanning is
possible, but solenoid does not actuate.

REASON
When DC units are above 7.5 V, their scan records behave
as AC.
When AC units are below 7.5 V, their scan records behave
as DC.
This is normal.
Defect power cell.
Fitting module has been replaced.
When voltage is 7.5 < 7.7 V, the module may lock up.
Feature included only with HyTronic modules version 1.8 and
below OR E-Tronic modules ver 1.3 and below.
Even with only "LOW BATTERY" (6x blinks after activation),
any RESET to the fitting causes it to behave as if in "DEAD
BATTERY" situation, i.e. possible scanning, but no valve
operation.
SOLUTION
This is normal for Commander. However, this could be an
indication of a short in a power system component.

Replace power cell
This is normal. The model and serial number are
programmed when fitting is first manufactured.
Use visual inspection cues to assist with identification,
including hose tag. Or contact TecTrue.
Increase or decrease power out of the given range
OR
Replacement module and check power system
components.
Later versions do not have this indicator. Instead the fitting
goes into "sleep mode" to conserve power, to prevent
rechargeable batteries from going into deep draw
(no longer chargeable).
Set power to proper level ASAP.
Always check power first before resetting if low power
situation is suspected.
