F8620/4 HIMA Industrial control module machine spare parts
F 6217 (0606)
Interferences of the module in low frequency range (10 Hz)External disturbing pulses in the range of 10 Hz, e.g. at pressure measurements of nearby piston pumps, can lead to temporary channel bit faults at the analog inputs. Internal hardwaretests carried out in the same rhythm are influenced by this pulses (fluctuations) in an adverseway. input channels could be interpreted as faulty and de-energized
Solution
Pressure sensors:
By internal damping via adjustable digital filters in the sensor disturbing pulses can be
minimized or eliminated.Use of low-pass filter H 7017:The high time constant of the low-pass filter eliminates the low frequency disturbing pulsesin the input current.
The low-pass filter may only be used in safety-related circuits with low-shut-down because in case of a failure in the filter (leakage current) themeasured values are reduced. The time relay of the fiter has to beregarded in calculating the safety time.
Note
Additional transmitter supplies, e.g. via front cable plug Z 7128, haveno disturbing influences on the operation of the module F 6217.
