ALAM signal is the logical sum of the individual channel alarms. Activation of the alarm detection in channels is made by switches which are accessible after opening the housing. elay or optorelay output.. Activation phase is adjustable with switches which are accessible after opening the housing. Inputs, outputs and power supply mutually galvanically separated. Intrinsically safe input circuit can work with any device, with intrinsically safe circuit of protection level ia or ib, that is installed in hazardous area of group I and areas 0,,, 0,, of group II endangered with explosion of any mixture, including proximity sensor, turbine flow sensor, connection or OC etc. Output circuits, ALAM signaling circuit and supply circuit can work with any nonintrinsically safe devices circuits of voltage Um=3V e.g. supplied from the 30Vac network. Separator can be installed in a room that is safe in terms of explosion and protected against access of persons not trained in maintenance and operating the transducer. Separator installed in a hazardous area can have a flameproof housing. Separator can be removed from the housing shortly after power in group I is turned off, because it does not contain any energy storage elements and do not become too hot. A 0 minutes delay is necessary in group II and III. danger zone In+ intrinsically safe zone +Usupp Out 3 In 4 In+ +Usupp In Inputs : resistance comparator, level sensor, proximity sensor, nonvoltage contact, OC transistor Note: Supply SBEx4S Out Pk Pk 7 8 Alarm PkA While the power is turned off output relay s contacts Pk (), Pk (78) and alarm contacts PkA () are opened. Purpose: Separator can be used to compare resistance, to work with reflective level sensor, proximity sensor or twowire pressure. It can transfer state of contacts or opencollector transistor to galvanically separated side. There is a possibility to adjust input switching current level and hysteresis width. These parameters should be given descriptively.

2 There is V on the input terminals. When using opencollector transistor as the separator driver terminals We+ 3 i We+ should be connected to collector. For not typical applications resistance or current switching thresholds as well as hysteresis should be specify in order. SW and SW switches (accessible after opening the housing) are used to inverse operation of output contacts. ON position means inverse working of output contact in this channel. If SW and SW switches (accessible after opening the housing) are set to ON, it activates input connection lines failure detection. OFF position means blocking alarm in the channel. For SW, SW OFF and for SW, SW ON output contacts and LED indicator work as follows: input signal increase above switching level + 0, hysteresis will cause shorting output relay contact (terminals Pk, Pk 78 ) and lighting of the green LED ( Pk, Pk ). Lighting up red ALAM LED and shorting of PkA; Pk contact means a break in the connection line (I<0,mA). Lighting up orange ALAM LED and shorting PkA; Pk contact means a short in the connection line (I>,mA). PkA; Pk alarm contacts are shared indication for all channels user should check which channel is related to the fault by looking at LED signaling. Note: to let short / open in sensor channel indication on input work properly (when working with contact or transistor) join parallel resistor 39 47k and serial resistor 0 0 to the terminals of the sensor (in Ex area).

SBEx4S/G4 SBEx4S/G4 can work as leakage security for not grounded electrical networks of, 4Vac or 4Vac (U ; U 4Vac) and 0 0Hz frequency. When network is off it acts as a security lock and after it switches as a central security function. It is made in specific version after agreement with the customer. The separator operates correctly as central security for circuits with voltage U when capacities of the line with regard to the ground do not exceed µf. In case of central security measuring circuit does not have to be intrinsically safe and in this case we suggest to use separator type SB4S/G4. It can handle circuits with U 4Vdc, U 4Vac. Type SB4S/G4 more accurately identifies leakage resistance even at capacities to the ground C 3μF.

III. SBEx4S/G00 The separator has ia protection level. This allows measuring circuit to remain powered with voltage (not greater than Ui=0V) even after exceeding the concentration of methane over %. The separator s power supply does not need to be switched off. Separator SBEx4S/G00 is used to control condition of the isolation in isolated electrical networks. Isolated networks marked with the IT symbol are characterized by isolating all active elements of the network from the ground potential. They ensure greater security from electric shocks because the current destruction is limited by very large network capacitive impedance to the ground. IT networks can have very large allowable grounding resistance. Separator SBEx4S/G00 can be used as: a) a leakageblocking security designed to control grounding isolation resistance in a voltageless state in intrinsically safe and nonintrinsically safe circuits, b) centralblocking leakage security or central leakage security for circuits in which voltage does not exceed 38V after switching on. These circuits after switching on the power are no longer intrinsically safe (Um>0V), c) centralblocking leakage security or central leakage security for circuits in which voltage does not exceed 0V. These circuits after switching on the power can still be intrinsically safe if Um 0V. SBEx4S/G00 separator can act as leakageblocking security used for ground isolation resistance control in nonvoltage state in threephase networks with isolated zero point of Fig.. with chokes e.g. ED00i 30V, 00V, 000V and 40V voltage, Fig.. without chokes for voltages to ground U 38V.

It blocks power supply when controlled circuit resistance drops below kω. Separator has three separated from each other contacts on nonintrinsically safe side. Closing first contact (terminal ) affects control circuits, and closing the other contact (terminal 78) affects signaling circuits. There is possibility to put second measurement channel in the same housing buy only with one output contact (terminal ) which affects control circuits. Contact with terminal can be used as redundancy for controlling or signaling which can improve reliability of the whole system. Terminals WE WE are separate, galvanically isolated, intrinsically safe circuits. One multiwire type A or B IEC cable or separate cables may be used to connect these circuits simultaneously. Separator SBEx4S/G00 in version for 30Vac voltages can operate as a centralblocking leakage security or central blocking security designed to control the resistance of the isolation toground in isolated onephase networks with voltage U=30Vac Fig.. For voltages U>0V measuring circuit is no longer intrinsically safe.
