Operating instructions
Function/assignment
Power supply, phase, see nameplate for voltage range
Protective earth
RS485 interface for MODBUS, RSA; SELV
RS485 interface for MODBUS, RSB; SELV
Reference ground for control interface, SELV
Function parameterizable (see "Optional interface functions" table)
Factory setting:
Digital input - high active, function: Disable input, SELV
- inactive: Pin open or applied voltage < 1.5 VDC
- active: applied voltage 3.5-50 VDC
Reset function: Triggering of error reset on change of state from "enabled" to "disabled"
Function parameterizable (see "Optional interface functions" table)
Factory setting:
Analog input 0-10 V / PWM, Ri=100 kΩ, function: Set value
Characteristic curve parameterizable (see input characteristic curve P1-IN), SELV
Function parameterizable (see "Optional interface functions" table)
Factory setting:
Analog output 0-10 V, max. 5 mA, function: Fan modulation level
Characteristic curve parameterizable (see output characteristic curve P3-OUT), SELV
Voltage output 3.3-24 VDC ±5%, Pmax=800 mW, voltage parameterizable
Factory setting: 10 VDC
short-circuit-proof, supply for external devices, SELV
alternatively: 15-50 VDC input for parameterization via MODBUS without line voltage
Status relay, floating status contact, common connection, contact rating 250 VAC / 2 A (AC1) / min. 10 mA,
reinforced insulation on supply side and on control interface side
Status relay, floating status contact, break for failure
green: status = good, ready for operation
orange: status = warning
red: status = failure
