10) microiswitches of programming:
- a. selection of the activation alarm function
in position 1 the alarm function is disabled
in position 0 the alarm function is enabled
- b. selection of the multiplying constant of tripping time
in position 1 K=10
in position 0 K=1
- c,d selection of the multiplying constant of tripping current
with c,d in position 0 K=0,1
with c in position 1, d in position 0 K=1
with c,d in position 1 K=10
- e selection of the type of functioning of the TRIP relay
in position 1 the relay is energized at rest
(FAIL SAFE)
in position 0 the relay is de-energized at rest
- f selection of the type of functioning of the ALARM relay
in position 1 the relay is energized at rest
(FAIL SAFE)
in position 0 the relay is de-energized at rest
