Settings Related to Tap Tracking

<CONFIGURE>  TapChgr: the type of tap changer the control is installed on.
Changing this setting will reinitialize all of the advanced tap changer settings in the
diagnostics menu to their defaults.

<CONFIGURE>  NeutOvRun: keeps the tap changer on for a period of time after
moving into neutral. This is active for Siemens tap changers only. Set to 2.0 for TLG
mechanisms; 1.7 for TLH mechanisms (typically above 400A). If in doubt, use 2.0 sec.

<ADV CONFIGURE>  Tap Alert: Enable/Disable tap tracking alerts.

<ADV CONFIGURE>  TapPosHold: PERM will retain tap position in memory after a
power down. TEMP will purposely lose tap position after a power down. In version 3.08
and up, this setting has been removed and the tap position is always retained in memory
after a power down.

<ADV CONFIGURE>  Tap Resync: when turned on, the panel will compare the
neutral signal with the tap position in memory and resynchronizes when the regulator
passes through neutral (if necessary). If there is a problem with the neutral signal timing
or the neutral light switch in the regulator tank, then turning this on will result in the
control losing its tap position and it will not resync. If turned off, the control will track tap
position correctly regardless of the neutral signal.

<DIAGNOSTICS>  R/LOnTime: maximum time to keep the tap changer motor running
before pausing for R/LOffTime.

<DIAGNOSTICS>  R/LOffTime: pause between tap changes for this amount of time.

<DIAGNOSTICS>  TapChgT/O: if the control runs the tap changer motor for
R/LOnTime and no operations count occurs, then after this many more seconds a Tap
Track Err OD alert is generated.

<DIAGNOSTICS>  TapIn: defines the operations count signal input line

<DIAGNOSTICS>  TapInType: defines the operations counter type

<DIAGNOSTICS>  TapInPulse: defines the minimum amount of time that an
operations count signal must be present in order for the operations counter to increment
(applies to Pulse type operations counters only).

<DIAGNOSTICS>  PreTapTime: measures load voltage before tap change

<DIAGNOSTICS>  PostTapTime: measures load voltage after tap change

<DIAGNOSTICS>  NeutralIn: defines the neutral signal input line

<DIAGNOSTICS>  NeutralCount: defines the number of different Neutral positions
(for use with LTC's only)

<COUNTERS>  Tap=: the tap position stored in the control's memory
