Commissioning - SWR ENGINEERING Envea FlowJam A Operating Instructions Manual

5. Commissioning

All operational controls required for the alignment
are shown in fig. 11.
Control elements:
• LED 1: Signal strength
• LED 2: Material flow
• S1: Switching between
working current / closed current
• S2: Coarse adjustment of sensitivity
• P1: Threshold level
• P2: Delay time
Switch S1
The position of switch S1 determines, whether the relay is attracted up or released at material flow.
Position "2" (off) causes alarm in case of material flow:
• material flow
• no material flow
Position "1" (on) causes alarm when there is no material flow:
• material flow
• no material flow
LED 1
The LED 1 (red) lightning shows the signal strength by its luminosity; that is, no lightning if no reception
signal (no material flow, no vibrations, etc.), weak lightning if low and strong lightning if intense reception
signal.
LED 2
The LED 2 (green) lights always up, if material flow is detected; this display is independent of the position
of the switch S1.
