minimum. 

Accuracy 

Amplitude 

Within ± 0.33% of full scale 
typical, ± 1% maximum when 
input signal is at the center 
frequency of the proportional 
value's passband. 

Phase 

3 degrees error, maximum. 

Channels 
enabled 

Certain configurations allow the 
user to enable only one channel 
of a channel pair. See discussion 
and graphs in the final pages of 
this datasheet. 

Filter tracking/ 
stepping (requires a 
valid speed signal) 

Initial condition 

Nominal filter set used. 

Switch from 
nominal to 
lower filter set 

Current shaft speed ≤ 0.9 x 
(Nominal Shaft Speed). 

Switch from 
lower to 
nominal filter 
set 

Current shaft speed ≥ 0.95 x 
(Nominal Shaft Speed). 

Switch from 
nominal to 
higher filter set 

Current shaft speed ≥ 1.1 x 
(Nominal Shaft Speed). 

Switch from 
higher to 
nominal filter 
set 

Current shaft speed ≤ 1.05 x 
(Nominal Shaft Speed). 

Shaft speed 
error condition 

Nominal filter set used. 

Alarms 

Alarm setpoints 

The user can set Alert levels for 
each value measured by the 
monitor and Danger setpoints for 
any two of the values measured 
by the monitor. All alarm setpoints 
are set using software
