Refer to Table 5.2, “Trip Configuration Details”. Measure the existing setpoint voltage (V
STPT
); use the equation below to calculate the new setpoint voltage. Adjust coarse and fine
potentiometers to produce calculated New V
STPT.
New Trip Current
New V
STPT
=
Old Trip Current
X Old V
STPT
Example:
Old V
STPT
= 7V
Old Trip Current
= 70kA
New Trip Current
= 80kA
80kA
X 7V
= 8V (New V
STPT
)
70kA

Use TP0 for zero volt reference (circuit common) for voltage measurements for trip
setpoint configuration.

NOTE
The LKAT
2
is supplied with factory configured trip setpoints configured as specified in the
LKAT
2
Worksheet at the time of order. If the trip setpoints are reconfigured in the field, the
customer must realize that the trip setpoints shown on the LKAT
2
Metering Unit nameplate
will no longer be correct. In this case, DynAmp suggests that the nameplate be changed to
reflect the new trip setpoint (following reconfiguration).
