level developments ELS-DR : Adjustable Levelling Switch, Dual Relay Output Features • Single axis levelling controller with dual relay output • Adjustable switching threshold from 0.2 to 4.8° • 'ZERO' button to set zero after installation • Small size and low power consumption. • No moving parts means no servicing and long life • High precision switching threshold • Mercury free and RoHS compliant • Sealed to IP65 andCE certified • Man lift platform levelling • Recreational vehicle auto-levelling • Roller shutter door controls • Container levelling • Can be readily customised to suit most applications A tilt switch with dual relay outputs designed primarily for levelling systems. The switching threshold is adjusted using the pcb mounted rotary switch. If the tilt exceeds the threshold with clockwise tilt, relay 1 will be switched on, and will switch off when the angle returns to zero (or below). Conversely if the tilt exceeds the threshold with counter clockwise tilt, relay 2 will be switched on, and will switch off when the angle returns to zero (or above). In this configuration the tilt switch can be used to drive motorised or hydraulic actuators to maintain a system in a level position. To Make installation easy, it can be mounted horizontally or vertically, and there is a switch to set the zero position after installation. The unit utilises a high precision MEMS sensing element and is available with and without temperature compensation, which improves the accuracy over a wider operating range.

level developments ELS-DR : Adjustable Levelling Switch, Dual Relay OutputOperating Instructions Setting the Relay Tilt Threshold Angle The tilt threshold can be adjusted to set the angle at which the relays will trigger. The range of adjustment will depend on the model purchased (see table). The tilt threshold is set via the small rotary switch on the PCB. The rotary switches have 16 positions labelled 0-9 and then A-F. This allows the trip angle to set with a range of 16 values between the maximum and minimum values. The switches can be adjusted with a small screwdriver. Once set, the lid...
