Prover Range of Operation (value of bits in hex):

0 = prover not selected

1 = prover is not running, but active

2 = prover running Ć past the 1st switch in forward leg

3 = prover is done with forward leg, returning at this time

Ć midĆrun value (bidirectional only)

4 = prover is returning on 2nd leg (bidirectional only)

5 = prover is done with run (BTR word 13/14 contains prover count value)

ON and OFF output values can be triggered by:

Frequency = 0Ć120,000

Percent of Fullscale = 0Ć32,767 (use LSD word 46, 50, 54, 58 only)

Acceleration = -32,768 Ć 32,767 (use LSD word 46, 50, 54, 58 only)

Total = 0Ć9,999,999

Direction = 0 (stopped), 1 (clockwise), 2 (counterclockwise)

(use LSD word 46, 50, 54, 58 only)

Overflow = 0 (output follows Overflow bit, BTR words 4 & 5)

Prover Range of Operation = 0Ć5 Ċ ON and OFF values must be different

(use LSD word 46, 50, 54, 58 only)

Prover Running = 0 Ċ Output is ON when the prover is actually counting.

unidirectional prover: ON from 2Ć5

bidirectional prover: ON from 2Ć3 and 4Ć5

Important: When any type of scaling is used (frequency or total),

outputs are always triggered by the actual value not the

scaled value. Outputs triggered by Total turn ON in < 100

s

and turn OFF in < 100

µ

s. All other ON and OFF times

are < 1ms.
