16.2 Setting of the operating time via the speed-interface board (option)
(refer to order-related wiring diagram CI S...KMS 14TP...)
With the speed-interface board the operating time (speed) can also be
pre-determined through an external signal, either analogue (command sig-
nal E3 = 0 - 20 mA or 4 - 20 mA) or binary (command signal n1, n2).
The simultaneous use of the analogue and the digital
operating time set signal is not possible!
.
Loosen 4 screws (8.1) and remove cover (figure U, page 23).
.
The speed-interface board (figure W) is situated directly above the logic
board. Depending on the version (with or without positioner), remove the
boards above it (cover plate, positioner board and additional board).
Setting
on logic board:
.
Check on the logic board whether the DIP switch S1, pos. 7 (nominal
output speed) is in position ”OFF”. If necessary, correct the switch position
(see clause 14, pages 18/19).
.
Set the potentiometer ”OPERATING TIME” (figure V, page 23) on the
logic board to the fully clockwise position (max. speed) to make use of the
entire range of operating time. If the minimal operating time (max. speed)
has to be limited to a higher value as the operating time possible by the
actuator (see technical data sheet), set potentiometer to this value (e.g. to
avoid water hammer).
Setting on the
speed-interface board:
When using the option positioner (see clause 15, page 20) set the selector
switch S2-2.2 (figure W) on the speed-interface board to position
‘positioner’. For all other versions the switch S2-2.2 has to be set to position
‘speed-interface board’.
