5.2 Switching the Device on
The device is activated and ready to operate as soon as supply voltage is applied. The readiness for
operation is signaled by the Power-LED.
5.3 Minimum-/Maximum Value Memory
A signal is measured at terminals 1 and 2. If the following measurement is smaller, the signal output at
the minimum value memory is updated at terminals 10 and 11. If the measurement is higher, the
respective value of the previous measurement is held and issued. The minimum value output is from
-10V to +10V.
A signal is measured at terminals 1 and 2. If the following measurement is larger, the signal output at
the maximum value memory is updated at terminals 12 and 11. If the measurement is smaller, the
respective value of the previous measurement is held and issued. The maximum value output is from
-10V to +10V.
A control signal of 10 ... 30VDC is required in order to reset the minimum and maximum values. In
order to delete the minimum value, the control signal must be applied to terminals 7 and 8. In order to
delete the maximum value, the control signal must be applied to terminals 9 and 8.
