The measuring principle is based on the occurring resistance change when moisting single-pole electrodes. The single-pole electrodes (see also section Accessories) are connected to the terminals and or MAX. If the is applied to A-A and the electrodes are wet, the output relay of the M-ENE is energized and the output relay of the M-ENE MAX is de-energized. The output relay of the M-ENE de-energizes if the electrodes are no longer wet. The output relay of the M-ENE MAX energizes if the electrodes are no longer wet.

M-ENS The M-ENS monitors levels of conductive liquids and is used for example for liquid level control in pump systems. It can be used for filling or draining tanks for example. SVR 430 85 F00 It is also suitable for monitoring the conductivity of liquids. The measuring principle is based on the resistance change sensed by single-pole electrodes. After the is applied to the terminals A and A, the output relay is de-energized. The probes must be connected to, MAX,. The output relay energizes if the liquid exceeds the maximum level ( and MAX wet) and de-energizes if the liquid level is below the minimum level (MAX and dry). Based on the measuring circuit there will be a response delay of approx. 50 ms at maximum sensitivity. Different levels in one tank can be controlled by up to 5 M-ENS without interfering with each other.

M-ENS UP/DOWN SVR 430 85 F00 The M-ENS UP/DOWN monitors levels of conductive liquids and other media, and is used e.g. for liquid level control in pump systems. The measuring principle is based on the resistance change sensed by single-pole electrodes. The output relay functions fill (UP) or drain (DOWN) can be selected on a front-face selector switch. If the "UP" function is selected, the output relay is energized until the MAX electrode becomes wet. Then it is de-energized and not re-energized until the electrode becomes dry. If the "DOWN" function is selected, the output relay is energized as soon as the MAX electrode becomes wet. It remains energized until the liquid level has dropped below the electrode. The electrodes can be connected to more than one M-ENS without interference.

M-ENN SVR 450 055 F0000 The M-ENN monitors levels of conductive liquids and is used for example for liquid level monitoring in pump control systems, for dry-running protection of submersible pumps or overflow monitoring of tanks. It is also suitable for conductivity monitoring of liquids. The measuring principle is based on the resistance change sensed by single-pole electrodes (wet or dry). Instead of electrodes, other sensors or transducers can also be used if their output quantities are different resistance values. The measuring, output and supply circuits are electrically isolated for potential separation and to prevent electrical interference. Due to the integrated ON- or OFF-delay, it is possible to set up time-dependent liquid controls using only two electrodes (, MAX). Different liquid levels in one tank can be controlled by up to 5 M-ENN (A version) without mutual interference.

Application examples fill drain SV 0 000 F 066 or onnection diagram M-ENN SV 0 000 F 069 SV 0 000 F 068 For commissioning, set both potentiometers (response sensitivity = R value and ON-delay = time value) to the minimum value (5) and select a suitable resistance range (sector). After all electrodes have been wetted by the liquid being monitored, turn the sensitivity potentiometer towards maximum value (00) until the relay energizes. If the relay does not energize, select a higher value (sector) on the device and proceed as before. Then it has to be checked if the relay de-energizes properly as soon as the electrodes and are no longer wet. Liquid levels higher than the maximum level electrode can be obtained by setting an ON-delay (TA = 0...0 s). Liquid levels lower than the minimum level electrode can be obtained by setting an OFF-delay time (TR = 0...0 s), e.g. for emptying tanks.

- Liquid level control with two alarm outputs - M-ENN UP/DOWN SVR 450 05 F000 The M-ENN UP/DOWN monitors levels of conductive liquids and media and is used e.g. for liquid level control in pump systems. The measuring principle is based on the resistance change sensed by singlepole electrodes. The function of the output relay -/4 can be selected by a selector switch on the front of the to fill "UP" or drain "DOWN". If the "UP" function is selected, the output relay is energized until the MAX electrode becomes wet. Then it is de-energized and not re-energized until the electrode becomes dry. If the "DOWN" function is selected, the output relay is energized as soon as the MAX electrode becomes wet. It remains energized until the liquid level has dropped below the electrode. The electrode inputs AL and AL energize/de-energize the correspopnding output relays RAL (-) and RAL (3-3). AL opens if contact RAL (-) is wet. AL closes if contact RAL (3-3) is wet. This way, two additional alarm outputs for exceeding or dropping below the normal level can be implemented in addition to the filling levels MAX and.
