SO 2-Ex 11
Electric control:
•
remote control (the output element of the EA is controlled with supply voltage) (SO 2-Ex), resp. SO
2-Ex with built-in controller - by feeding of unified signal
•
Adjustment of the limit positions
Precision of limit position switches .........................adjustment working stroke ± 5% of max. set stroke
Additional position relays adjustment ................................ ..cca 1 revolution beneath the limit switches
Hysteresis of position switches ................................................... max. 5% of the max. stroke of the
chosen range
Failure of the customer to specify the particular operating speed parameter in more details the speed
are set to the value according to the 3
rd
degree of the selected range – see Table 2.
Adjustment of the torque switches:
If other adjustment not specified the switching torque is set to the maximum value with tolerance of
±10 %.
Switches – standard version D38:
supply voltage ...................... 250 V(AC); 50/60 Hz; 6(4) A; cos
