CL-AC1 is powered by AC voltage at 24 V AC. The terminal
designations are "L" and "N".
CL-AC2 is powered by AC voltage at 85 to 264 V AC, 50/60
Hz. The terminals are labelled with "L" and "N".
CL-DC1 is powered by DC voltage at 12 V DC. The terminals
are labelled "+12 V" and "0 V".
CL-DC2 is powered by DC voltage at 24 V DC. The terminals
are labelled "+24 V" and "0 V".
The terminals for the power feed are the first three terminals
on the input side.
Data is retained even after the logic relay power supply is
switched off. (retentive data)
The following data is retentive:
• CL circuit diagram
• Parameters, setpoint values
• Texts
• System settings
• Password
• Actual values of marker relays, timing relays, counters
(selectable)
Each line in the circuit diagram is a rung. CL-LSR/CL-LST and
CL-LMR/CL-LMT can take 128 rungs.
