Doc. No.: 560001 EGPage:28 Ed.1" 08-2014From ser. no.:E N G L I S HThe digital input is used to read a light sensor (actually an analogue input, from which a digital signal is taken using the parameter orthreshold of the light sensor). The light sensor may be located:• in the door stop,• inside the cold room or cabinet.In the fi rst case, , the sensor signals the opening and the closing of the door, because, with the door open, light is signalled, andwith the door closed, darkness is signalled (the sensor is located in the door stop and thus will be shadowed when the door isclosed). The inside light will be automatically switched on when the door is open and switched off when the door is closed. Thelight stays OFF for a minimum time of 5 seconds, to avoid rapid, successive impulses of the light relay.To select this operating mode, set AF=0.In the second case, the light sensor signals the opening of the door of the cold room or the cabinet due to the outside light thatthe sensor detects, thus activating the inside light. The closing of the door is measured by time, as the light inside the cold roomor cabinet will illuminate the sensor. After time AF (greater than 0), the inside light is switched off for 5 seconds. If the light sensorsignals darkness, the door must be closed and the light will therefore remain OFF. Otherwise, the door is still considered open andthe light is switched on again. To select this operating mode, set AF>0.A4 =12 Activation of the AUX outputThe digital input is used to activate/deactivate the AUX output, if confi gured with parameter H1 or H5, with the following logic:Digital input AUX outputopen deactivationclose activationTab. 7.hThe output is activated/deactivated on closing/opening the contact, to make this operating modecompatible with the presence of the AUX button and the control signal from the supervisor.Note: if more than one digital input is configured as AUX, the open status occurs when at least one of the inputs switches to openstatus.A4 =13 Door switch with compressor and fans off and light not managed.Same as for A4=5, with the difference that the light output is not modifi ed.Note:1. the door management algorithm depends on the parameter ‘Ado’.2. if more than one digital input is configured as the door switch, the door open status will be considered when at least one of theinputs is open.A4 =14 Door switch with fans only off and light not managed.Same as for A4=9, with the difference that the light output is not modifi ed.Note: for A4/5= 13 or 14: the Ado door management algorithm is used in both cases.Default: A4=0 => Digital input not active (for all other models).The table below summarises the functions of the digital input corresponding to the value assigned to the variable A4.Value of A4 Function Function active LED on0 input not active1 immediate external alarm open = alarm open2 delayed external alarm open = alarm open3 for model M, select probes open = probe selected by parameter /tI closed =fi rst probe enabled3 other models, enable defrost closed= enabled4 start defrost closing = defrost request5 door switch with compressor and fans OFF open = door open6 remote ON/OFF open = instrument off7 curtain switch closed = curtain closed8 low pressure switch open = low pressure9 door switch with fans OFF only open = door open10 direct / reverse open = direct11 light sensor above the threshold = off12 activation of AUX output open = deactivation13 door switch with compressor and fans off, light notmanagedopen = door open14 door switch with fans only off, light not managed open = door openTab. 7.hNote:• if more than one digital input is confi gured in the same way, the activation of the associated function will be enabled if at leastone of these is open.• for control with two compressor steps (with or without rotation, H1=12 or 13) the function associated with the digital inputs isactivated on both.A5: Confi guration of the second multifunction digital input.For this parameter the same description relating to parameter A4 is valid, obviously referring to the second digital input. Default:A5=0 => Digital input not active.A6: Stop compressor from external alarm (multifunction input)The meaning of this parameter is similar to that of parameter c4 (duty setting).If an external alarm occurs (immediate or delayed), the compressor works for a time equal to the value set for parameter A6 (inminutes), while it remains OFF for a fixed period of 15 minutes.Special cases:A6=0 the compressor is always OFF;A6=100 the compressor is always ON. |
