OFFSET in PROGRAM mode while external offset depends on the analog input Ain Toggling between manual and external offset is done by pressing and holding 4 and then pressing The sign states that all zones are temporarily disabled by user by pressing and holding lt and then pressing Esc The zones can be disabled externally by input In2 This is denoted by the sign When a zone is disabled the heating of this zone is powered off Thus the user can quickly turn off heating by disabling all zones from the console or externally through input In2 The heating zone parameters are located in the ZONE menu The ZONE menu can be reached in two ways When in MONITOR mode in MAIN menu pressing the Esc button will put the display into ZONE menu The second way is to select a new value of the PROGRAM No parameter in PROGRAM mode In ZONE menu the user can watch and change the value of each heating zone in the same manner as in the MAIN menu When no cursor is present the display is in MONITOR mode and the current measured values for each zone is indicated In PROGRAM mode the user can change the set value for any zone MONITOR mode ZONE menu PROGRAM mode ZONE menu lt 1 gt 23 4 lt 5 gt off any key but Esc lt 1 gt 23 lt 5 gt 9 8 lt 2 gt 43 1 lt 6 gt off lt 6 gt 29 1 lt 3 gt off lt 7 gt 33 9 Ese lt 7 gt 33 8 d H q _ oo lt 4 gt 20 0 lt 8 gt off lt 8 gt 59 8 Zones are

5. n this value should be the number of items in one cluster that the machine blows If In1 is connected to the sensor detecting the incoming preforms then the value of XX should be 1 Thus the counter will represent the number of produced items To reset the counter the user must select the Items Imp parameter press and hold 4 and then press Esc Using the same parameter the user can toggle the language between English and Bulgarian by pressing and holding 4 and then pressing The third parameter on the main menu reads Cycle time in MONITOR mode and Velocity in PROGRAM mode When in MONITOR mode it shows the period of time between two preforms on In1 to be produced 1 e this is the productivity of the machine In PROGRAM mode the user can change the value in percent to set by the means of the analog output Uout Iout the proper speed of the chain Status N A will indicate that the cycle time has not yet been computed or the chain is not moving The sign in front of the measured value means that the movement of the chain is temporarily disabled by user Toggling between enabling and disabling a parameter is done by pressing and holding lt and then pressing Esce The OF FSET parameter allows to add an offset up to 50 to all heating zones without the need to change each of the heating zones values in ZONE menu The offset can be manual OFFSET M or external OFFSET A Manual offset is set directly by the parameter
