CB-100-2 19
– Max. input current: <25mA (current signal)
– Max. input voltage: ±24VDC (voltage signal)
– Input impedance:
Voltage range: 22kΩ
Current range: 120Ω
Digital outputs
• Function
– X12:4:DO3(Comp. 2)
External control: without function.
With extension module: Start of the 2nd com-
pressor.
• Technical data
– Output signal: 24VDC (minimum 21VDC)
– Max. output current: 140mA.
(The maximum available total current is 140mA,
either individually or as the sum of digital outputs
and the +24VDC power supply on the user
side).
Analogue outputs
• Function
– X11:3:AO1 (Fan)
External control: without function.
With extension module: control signal for con-
denser fan 0..10V.
– X11:4:AO2
Reserve.
• Technical data
– Output signal: 0..10V.
– Max. output current: 10mA, with short-circuit pro-
tection.
– Output impedance: Voltage range ≥1kΩ.
Relays
• Function
– X14:1:Relay 1A → X14:2:Relay 1B
Compressor is ready to operate.
– X14:3:Relay 2A → X14:4:Relay 2B
Compressor is running (factory setting) or no error
can be configured via the parameter logic of out-
put DO1.
• Technical data
– Potential-free relay.
– Switching current range: 1mA to max. 3A of res-
istive load
– Switching voltage range: 5VAC to max.
250VAC or 30VDC
– Protection against inductive or capacitive loads
must be provided by external measures.
Information
The STO inputs must be activated to allow the
compressor to start!
STO (input circuit)
• Function (see chapter Safe Torque Off (STO), page
24)
– X10:1:Input A and X10:3:Input B.
STO inputs (Safe Off Torque).
Inputs must be switched simultaneously.
– X10:2:Common and X10:4:Common.
Terminals are connected internally. Thus, only
one cable core is required.
• Technical data
Typical input current at 24 V: 9 mA
– Status:
Off (recommended): 0..5VDC
Undefined: 5..21,6VDC
On (recommended): 21.6.. 26.4VDC
– Max. input voltage:±30V DC
STO status
• Function (see chapter Safe Torque Off (STO), page
24)
– X10:5status A → X10: 6:StatusB
This output is active (closed), if the STO circuit is
in the safe state, i.e., if the FI does not allow the
motor to produce a torque.
• Technical data
– Potential-free semiconductor relay.
– Max. voltage: ±30V.
– Max. output current: 150mA.
– Thermal overload protection integrated.
– Resistance between the output terminals:<6Ω.
