Operating instructions
Function / assignment
Analogue input 1, set value: 4-20 mA; Ri = 100 Ω, parametrisable curve, only for use as alternative to input
Ain1 U; SELV
Digital input 1: Enabling of electronics,
Enabling: Pin open or applied voltage 5-50 VDC
Disabling: Bridge to GND or applied voltage <1 VDC
Reset function: Triggers software reset after a level change to <1 VDC; SELV
Digital input 2: Parameter set 1/2 switching, depending on EEPROM setting, the valid/used parameter set can
be selected via the bus or via the digital input DIN2.
Parameter set 1: Pin open or applied voltage 5-50 VDC
Parameter set 2: bridge to GND or applied voltage <1 VDC; SELV
Digital input 3: Controller function of integrated controller; depending on EEPROM setting, normal / inverse can
be selected for the controller function of the integrated controller via the bus or the digital input
Normal: Pin open or applied voltage 5-50 VDC
Inverse: bridge to GND or applied voltage <1 VDC; SELV
Analogue input 2, actual value: 0-10 V, Ri = 100 kΩ, parametrisable curve, only usable as alternative to input
Ain2; SELV
Fixed voltage output 20 VDC, +20 V +25/-10%, max. 50 mA, short-circuit-proof, power supply for ext.
devices (e.g. sensors); SELV
Alternatively: +24 VDC input for parametrisation without mains power
Analogue input 2, actual value: 4-20 mA, Ri = 100 Ω, parametrisable curve, only for use as alternative to input
Ain2 U; SELV
Analogue output 0-10 V, max. 5 mA, output of current motor level control coefficient; parametrisable curve; SELV
