hysteresis is 2.5% of the measurement range.
At outputs F1 and F2 voltages of 0.03 volts up to 1 volts are detected.
Below the switching thresholds the relays are in the working state, the relay contacts are
opened. The corresponding light-emitting diodes (LED) light below the switching
thresholds.
On exceeding the thresholds or with the failure of the supply voltage U
B
the relay contacts
close. The exceeding of the threshold is signalled by the switching off of the LED.
Special variants as U/I-converters or peak value display with voltage input 0...5V are
optionally available.
Functional Diagram
Through the layout of jumpers two operating modes ("A" and "B") can be selected:
Mode "A" : (actual value-mode)
Signal-sequence: Amplification, peak value storage
The threshold indicator reacts to the actual value.
The actual value is shown on terminal 6.
The peak value is shown on terminal 7.
Mode "B" : (Peak value-mode)
Signal-sequence: Peak value storage, amplification
The threshold indicator reacts to the peak value.
The peak value is indicated (with the amplification selected) on terminal 6.
At terminal 7 the peak value with the amplification "1" is indicated.
The maximum output voltage on the peak value display (terminal 7) is limited to 5
volts. The maximum output signal on terminal 6 amounts to +10 volts.
