The PLC 1336-L6 is the logic interface board for the main control boards on the 1336 PLUS / PLUS II series AC drives. It is available as a spare part and is not repairable. 1336 PLUS and PLUS II series drives are available for 0.5 to 600 Horsepower (0.37 to 448 kW) output power ratings. The location of the 1336-L6 logic interface board is on the main drive control board, beneath the programming/display board. It provides a method of interfacing different commands and signals to the drive by means of contact closures. Six separate versions of the logic interface board are available. The 1336-L6 provides a 115 Volts AC interface. Inputs to the 1336-L6 are made through connections on Terminal Block 3 (TB3). The 1336-L6 has nine control inputs and the function of each can be selected through programming. The 1336-L6 does not support encoder feedback. The operating temperature range for the 1336-L6 is 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) at 5 to 95% non-condensing relative humidity. The board is conformally coated to protect the board from moisture and chemical contaminants in the environment. To prevent operator injury and equipment damage, supplied power to the drive should be removed before any maintenance activities - including board replacement and wire connection/disconnection - are performed. Since drive components are also vulnerable to electrostatic discharge, standard precautions for static control should be followed at all times.
