˙ ANALOG OUTPUT MODE
O Analog output setting : The second figure in triple digits LED indicates
output mode in the initial setting.
Output mode is fixed by rated pressure.

˙ SWITCH OUTPUT MODE
O Switch output can be set when blinking red LED indicates (SW2) in the intial setting.
O The mode is set at “Separate (H/H), 1” prior to shipment. The mode is initialized at “Separate (L/L), 4” when rated pressure is set at “-12P” or “-12F” (negative pressure).

Note 1. In the Separate Mode, setting 1 corresponds to SW1, and Setting 2
corresponds to SW2.
Note 2. In the Window Comparator Mode, the minimum value for SW1 and SW2
corresponds to Setting 1 and the maximum value corresponds to Setting 2.
