Keyphasor Operational Test - GE Bently Nevada 3300/03 Operation Manual

3300/03 System Monitor Operation Manual

10. Keyphasor OPERATIONAL TEST

The following test procedure for Keyphasor transducer 1 is also applicable for testing
®
Keyphasor transducers 2 through 4.
®
The machine associated with the Keyphasor transducer under test should be running during
®
this procedure. If the machine is not turning, simulate the operating machinery input at
approximately the same frequency as the shaft rotating speed, with a function generator or TK3
test kit.
1. Measure Keyphasor 1
®
power at the KPH1PWR
terminal on the power input
module (PIM). If -VT is -24 V,
the voltage should read
between -23.2 and -24.2
Vdc. If -VT is -18 V, the
voltage should read
between -17.40 and -18.30
Vdc.
