CONNECTiNg TO THE M4-ExTENSiON PANELS
• The M4-CNC is equipped with a 6-pin phone socket (RS485) to connect to extension panels and XSIG (4-20mA remote set point
Inteface). The M4-Extension is equipped with two 6-pin phone sockets to connect to M4-CNC and an additional M4-Extension.
• Set each Extension to a different letter (EXT-A or EXT-B). The M4-CNC will assign the stage letters based on the extension letter
selected.
• Extension A will operate stages E - J and all the LEDs will be Green. However, Extension B will operate stages K - P and all the
LEDs will be Red. See "M4-Extension Layout" on page 5.
• Configure the Modulating and Sequencing Output Types after connecting the Extension panels to be able to configure their outputs.
See "Modulating Output Type" on page 18
• Only use the cable provided for proper operation.

CONNECTiNg TO THE xSig
• The M4-CNC is equipped with a 6-pin phone socket (RS485) to connect to extension panels and XSIG (4-20mA remote set point
Inteface). The XSIG is equipped with two 6-pin phone sockets to connect to M4-CNC and an additional M4-Extension.
• Set Sensor Type to either of the two EMS options. See "Sensor Type" on page 16.
• The interface must be ordered separately.
• Only use the cable provided for proper operation.
