• LED for displaying the operational status of the valve
LED lights up for - current flow through the valve solenoid
LED does not light up for - no operating voltage
- input signals below 2% and zero-point switching
activated
• Operating voltage: 24 VDC
• Protection class: IP 65 for Type 1094-PMR plug-in control electronics (cable plug
electronics)
• ramping potentiometer R
3
for the adjustment of a delay time within the range of 0 to
10 s, in order to dampen sudden changes of the set-value (increasing and
decreasing ramps have the same delay)
• monitor output for testing the momentary coil current (1 mV monitor signal = 1 mA coil
current); this current is, for example, useful when setting the current values

NOTE
ATTENTION!
We recommend the use of the Bürkert Power Supply Type
1610 for the voltage supply, as this has been specially
designed for the Type 1094 electronics.
If you make use of another power supply, maintain the
operating voltage range between 24 V to and a maximum of
28V, together with a residual ripple < 10%.
If you are using a switching power supply, take into
consideration their tendency to oscillate with inductive loads
(e.g., the solenoids in the valves).
