Bitzer CM-SW-01 Technical Information

ST-150-4 37
All screw compressors
Analogue signal for capacity
control
0 .. 10VDC, ±2% at 100% with max. 1mA
or 4 .. 20mADC, ±2% at 100%, 500Ω resistor in parallel
linear control signal required
This type of control is particularly suitable for systems with simple controllers
equipped with an output for 0 to 10 V and with a relay.
Terminal strip CN14
All screw compressors
Modbus connection
0 .. 10VDC, linear control signal required
Modbus RTU, RS485, detailed description see BEST SOFTWARE.
Cables at L1, L2, L3 marking on the CM-SW-01 or at the fixed connectors located below
Operating recognition monitor-
ing, part-function of rotation dir-
ection monitoring
recognition range: 20 .. 135Hz at 83 .. 690V
time delay after activation of input signal of safety chain at CN2:3: 7s
3.3.1 Voltage supply of the peripheral devices
The compressor module internally supplies voltage to
peripheral devices (solenoid valves, slider position in-
dicator, oil and oil filter monitoring and/or oil heater)
and to the terminal strips CN7 to CN12.
3.3.2 Rotation direction monitoring fuse (F08)
The HS. and CS. compressors incorporating the com-
pressor module are equipped with the F08 fuse in the
terminal box. It protects the rotation direction monitor-
ing lines between terminal box and module housing.
Such a fuse is also required with open compressors
between module housing and motor terminal box when
the rotation direction monitoring function of the com-
pressor module is used.
Technical data of the installed fuse:
• Rated current 1A
• Release speed FF (very quick acting)
• Rated breaking capacity of 50kA at 700VAC
• Dimensions 6.3 x 32 mm
3.4 Available cable bushings into the module housing
