Note 1) This product is for dry air. Use in clean air, and be sure
that drain and oil content does not flow into the product.
Note 2) Use dry air to prevent condensation when operating at low
temperatures.
Note 3) Manual override is available only for DIN terminal type.
Note 4) Vibration resistance: No malfunction occurred in a
one-sweep test between 8.3 and 2000 Hz. Test was per- formed at
both energized and de-energized states to the axis and right angle
directions of the main valve and armature (value at the initial
state).
Note 5) DIN terminal type: Applicable to dusttight and low jetproof
(IP65).
