Page 12: Detailed Instructions
Page 12/24 Operating Instructions BA 7020 6. DETAILED INSTRUCTIONS 6.1 Functions in standard mode: These operation instructions concern the standard mode. The DIP switches are used to define the most commonly required configurations. In Modbus mode, the user can carry out additional advanced settings. The advanced settings are explained in a separate set of operating instructions: "Baelz 7020 Digital Positioner - Operating Instructions for Modbus Mode" In standard mode, the following functions are predefined: ● The setpoint actual value is supplied to both analogue outputs (both can be connected). -

Page 14/24 Operating Instructions BA 7020 6.3 Details on DIP switches: DIP 1 and DIP 2: are interpreted together DIP 1: 0 = voltage → DIP 2: 0 = 0-10 V or 1 = 2-10 V. DIP 1: 1 = current → DIP 2: 0 = 0-20 mA or 1 = 4-20 mA. Either a voltage source can be connected to the U-terminal or a current source to the I-terminal. - Page 15 Page 15/24 Operating Instructions BA 7020 DIP 11: DIP switch 11 defines the mode of operation: 1 = Modbus mode, 0 = standard mode. Standard mode is used to apply predefined normal settings. DIP 12: Starts an initialisation run when switched from 0 to 1. If DIP 12 is left in position 1 when the 7020 positioner is switched on, an initialisation run will not be startet.

Page 19/24 Operating Instructions BA 7020 6.7 Operational modes and operating options 6.7.1 Standard operation using DIP switches The DIP switches can be used to carry out standard configurations and operations (see Fig.Fig. 6 page 13). When DIP switch 11 is set to 0, the 7020 is in the standard operational mode. In standard mode, all DIP switches are active and the functions of the Baelz 7020 can be individually adapted. -
Page 20: Errors
Page 20/24 Operating Instructions BA 7020 7. ERRORS 7.1 Error after an initialisation run Following a successful initialisation run, only the green LED is lit. If the red LED is flashing, this indicates an error following an unsuccessful initialisation run. The first error to occur during initialisation is shown. If the green LED is lit, the unit had already been initialized before the current initialisation run. If the green LED is flashing, the unit had not been successfully initialized previously. -
Page 21: Error During Normal Positioner Operation
Page 21/24 Operating Instructions BA 7020 7.3 Error during normal positioner operation The green LED is lit during normal positioner operation. A flashing red LED shows an error during normal positioner operation. For this, DIP switch 12 must be set to 0. The red LED shows errors during positioner operation as follows: ( = long flash, = short flash) Error code 1: interval interval etc. -
Page 22: Spare Parts
Page 22/24 Operating Instructions BA 7020 8. SPARE PARTS When ordering accessories or spare parts, please refer to the name plate on the positioner.
