The following equations apply:
XX = Out of range diagnostic
I = Input
ECLS = External Current Limit
Setpoint
VDC = Volt Direct Current
mA = milliamps
ECLS -vs- Input (VDC)
ECLS -vs- Input (mA)

For RTAC Units Voltage Signal Current Signal
As generated from external source Vdc=0.133*(%)-6.0 mA=0.266*(%)-12.0
As processed by Tracer CH530 % = 7.5*(VDC)+45.0 % = 3.75*(mA)+45.0
As a graph this yields the following:
For input signals beyond the 2-
10VDC or 4-20mA range, the end of
range value is used. For example, if
the customer inputs 21 mA, the
ECLS limits it self to the
corresponding 20 mA ECLS.
