The S1 switch toggle exists on the Arm7 main control board, but does not exist on the M4 main control
board. For the Arm7 main control board, you need to set the switch toggle. For the M4 main control
board, you just need to verify the settings against the cooling device initial configuration table.
Procedure
Step 1
Check the DIP switch settings for each 30 kW chilled water precision air conditioner by
referring to the initial DIP switch configuration table for the main control board of the 30 kW
chilled water precision air conditioner.
Step 2
(Optional) If any DIP switch setting is inconsistent with the initial setting, change it to the
initial setting.
Disconnect the power supply before setting the DIP switch.
