2 HYCONTROL CAPACITIVE LEVEL SWITCH RANGE Hycontrol ME capacitive level switches provide simple, accurate and reliable level control for a wide range of applications. They are suitable for use on liquids, solids, slurries, pastes, granules, powders and pellets in high temperature, high pressure and corrosive environments. Unlike some other capacitive switches, this unit works independently of the tank walls using an integral grounding sleeve without the need for a reference probe, which enables it to be used in concrete, plastic or other non metalic tanks. This technology also provides an ideal solution for interface detection applications such as oil on water and liquid detection underneath a layer of foam. CAPACITIVE SWITCH FEATURES Easy installation through a 1 BSP process fitting High corrosion and chemical resistance as standard options Universal design can be used for high or low level detection Multiple versions with rod and cable to simplify mounting options High temperature versions up to 0 C Low maintenance technology with no moving parts Hazardous area certified versions ATEX approved Adjustable sensitivity for a wide range of products Adjustable time delay to stop spurious signals from surface ripple Anti-static probes for plastic pellet applications with high static probability Remote electronics option for high vibration applications Interface level detection for difficult applications CONSTRUCTION 1.

10 ADJUSTMENT COARSE CALIBRATION DELAY FUNCTION SETTING With the probe in contact with the being detected, set the SENSITIVITY ADJ pointer to position H and then using a blade screwdriver set the COARSE adjustment until the INDICATOR lamp is on. Rotating the COARSE adjustment clockwise and counter-clockwise will turn the INDICATOR lamp on and off. Ensure the lamp is on before moving on to adjusting the sensitivity. SENSITIVITY ADJUSTMENT This feature is used to stop any spurious signals to the switch from surface ripple or agitation of the product. It also protects the relay from premature wear by eliminating contact chatter by adding a small time delay from when product contacts the probe. The factory setting is zero seconds with the DELAY screw fully counter clockwise. Turning the screw in a clockwise direction introduces a delay between the INDICATOR lamp coming on and the relay changing its state. After setting the COARSE calibration the INDICATOR lamp will switch on when probe is touching the and off when in free air. Make sure the probe is in contact with the and then turn the SENSITIVITY ADJ knob clockwise until the INDICATOR lamp turns off. Set the SENSITIVITY ADJ pointer half way between H and the point that the INDICATOR lamp switches off.

11 INSTALLATION GUIDE A B A B Process connection mm max. Ø100 B L L>30mm ME11 ME60 A The grounding sleeve must be mounted to protrude at least 30mm from the vessel wall. For the ME60 type to be mounted properly the vessel walls should not exceed mm thickness. To prevent false readings on solids applications it is best to make sure the flows symmetrically. If the inlet is not located in the centre portion of the tank roof, check the flow pattern (a angle) of your and place the probe in the Appropriate location. ME 300mm ME40 ME60 If the probe is mounted on the top, make sure the length of probe is enough to touch the highest level of raw. The ME type must have at least 300mm from the silo wall. The ME60 type is usually Located at the lower position. For Non-Stationary or that will be vibrated a separate control unit such as the ME40 type is recommended. Where possible install the probe away from the inlet to reduce the risk of inflowing damaging the probe. If the probe is near an inlet, we recommend placing a protective cover 00mm above the probe. The cover should be parallel to the probe and the same length. 10

12 INSTALLATION GUIDE 300mm 300mm If multiple probes are mounted In the same vessel they must be separated by at least 300 mm to reduce probe to probe interference. The probe should not be mounted underneath a liquid inlet otherwise it will switch on erroneously. If the tank is equipped with an agitator, please use the timedelay function to stop spurious signals 0L The cable inlet should face downward to avoid rainwater ingress. Mounting the probe at a 0 incline optimizes the results and increases the switch sensitivity. Mounting the probe at top of tank will help avoid bridges from forming and reduce false alarms. 11
