CPS-2 SIGNAL CONNECTIONS
 
Beck Group 14 drives equipped with the 
Contactless Position Sensor (CPS-2) are shipped 
ready for installation.  They are engineered to 
match the mA or V dc feedback range in your 
system.
 
Customer connections for feedback signal 
wiring on each CPS-2 model are described in 
the following diagrams and paragraphs.  Refer to 
Table 11, page 46, for output signal ranges, output 
terminals, range changing resistance values, and 
terminals to which the ranging resistor or jumper 
is connected.
 
To verify that the feedback signal range 
is correct for your drive, connect a mA / V dc 
multimeter across the appropriate terminals 
(check model number on CPS-2 transformer and 
Table 11, page 46, for correct terminals CC, DD, 
or EE).  Use the Handswitch to operate the drive 
throughout its full travel.
NOTE:  Ranging resistors must be connected 
to the control drive output terminals.  If a 
ranging resistor change is required, it may 
be obtained locally.  If resistors with ±1% 
tolerance are not available, they can be 
ordered from Beck.

Terminal Connections
 1. A single 4–20 mA current output is available 
between terminals EE (+) and CC (-) when 
driving into an external load between 250 and 
800 ohms.  No ranging resistor is required.
 2. For 4–20 mA and / or 1–5 V dc output, 4–20 
mA is available across EE (+) and DD (-); 500 
ohms is the maximum external load (for larger 
loads see Item 1 above).  A 1–5 V dc signal is 
available across DD (+) and CC (-) into a 12 
K ohm resistive load when the circuit between 
EE and DD is completed.
4–20 mA Signal Output
Dual Signal Output
Option 3, Open / Close 
Direct AC Control
 
Customer must supply three wires to directly 
control the drive motor direction:  One 120 V ac 
line for Retraction (terminal M), one 120 V ac 
line for Extension (terminal N), and one neutral 
(terminal B).
240 V ac Operation
 
All of the options described above are 
available for 240 V ac operation instead of 120 
V ac operation.  In all cases, the power neutral is 
Option 4, Multi-Position
Direct AC Control with Cam-Operated 
Switches to Stop Drive Travel
 
Customer must supply three wires to directly 
control the drive motor direction:  One 120 V 
ac line for Retraction (terminal M), one 120 
V ac line for Extension (terminal N), and one 
neutral (terminal B).  Up to five intermediate stop 
positions may be specified, each requiring an 
additional 120 V ac line.
replaced with Line 2 of the 240 V ac, and the 120 
V ac line is replaced with Line 1 of the 240 V ac.
