Use cover 09709 for unused pressure-gauge aperture. he pressure gauge to indicate the room pressure must be connected to the actual value connection. dditional information Fitting instructions V 08 VV technical manual 7 000 00 Description of operation he low pressure amplifier converts the measured pressure difference to the pneumatic standard signal (0...0 bar). his signal is compared to the adjustable pressure signal for the setpoint X s. he proportional/integral controller compensates for the control deviations with no persistent error. he setpoint X s on the controller can be adjusted externally via connection, with the set value becoming the minimum limitation. Note: he pressure to be regulated must always be connected to the + connection. his is also true for negative pressure control. he change from positive to negative pressure control takes place exclusively by means of the setpoint. he direction of action can be changed from B (factory setting) to using a switch. ntended use his product is only suitable for the purpose intended by the manufacturer, as described in the Description of operation section. ll related product regulations must also be adhered to. Changing or converting the product is not admissible. Engineering and fitting notes Crosswise mounting is not permitted. Disposal When disposing of the product, observe the currently applicable local laws. ore information on materials can be found in the Declaration on materials and the environment for this product. / Right of amendment reserved 07 Fr.
