■NOTE ○Follow the instructions given below when designing, selecting and handling the product. ●The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed. ∗Product specifications •The direct current power supply to combine should be UL approved as follows. Circuit (of class 2) which is of maximum 30Vrms (42.4V peak), with UL 1310 class 2 power supply unit or UL 1585 class 2 transformer.

●Product handling ∗Installation •Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws and brackets may be broken. If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws. (Refer to "Mounting and Installation" on page 14 to 16.) •Do not apply excessive stress to the product when it is mounted with a panel mount.
Page 8
∗Wiring •Do not pull the lead wires. In particular, never lift a product equipped with fitting and piping by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction or to be off the connector. •Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them. Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.

•Do not expose the product to direct sunlight. If using in a location directly exposed to sunlight, shade the product from the sunlight. Otherwise failure or malfunction can result. •Keep within the specified fluid and ambient temperatures range. The fluid temperature range and ambient temperature range is 0 to 50 Operation under low temperature leads to cause damage or operation failure due to frozen moist in the fluid or air.

Names and Functions of Individual Parts Name Description Power source display (green) Turns on when power is supplied. Flashing interval depends on the flow value. Flow display (green) As flow increases, flash interval is shortened. The light turns to red when rated flow is exceeded. Body Product itself.
■Definition and terminology Terminology Definition It reads "full span" or "full scale", and indicates varied analog output F.S. (Full span, Full scale) range at rated value. For example, when analog output is 1 to 5 V, F.S. = 5[V] - 1[V] = 4[V], (ref. 1%F.S. = 4[V]x1% = 0.04[V]) Non-linear output Indicates non linear output.
Mounting and Installation ■Installation Panel mounting •Insert Panel Mount Adapter B (supplied as an accessory) into Section A of Panel Mount Adapter A. Push Panel Mount Adapter B from behind until the display is fixed onto the panel. The pin of Panel Mount Adapter B engages the notched part of Panel Adapter C to fix the display. •The switch can be mounted on a panel with a thickness of 1 to 3.2 mm.

Bracket mounting •Fasten the bracket mounting screws to a torque of 0.5±0.05 Nm. Without flow adjustment valve With flow adjustment valve (using ZS-33-M) (using ZS-33-MS) DIN rail mounting •The tightening torque for DIN rail mounting screws and joint screws should be 0.4±0.05 Nm. -15- No.PF##-OMJ0016...
■Piping •Ensure tightening torque is correct when installing piping. •Refer to the following table for the appropriate torque values. •Hold the metal part with a spanner when piping. Nominal size of screws Appropriate torque Nm Rc1/8 7 to 9 Rc1/4 12 to 14 •For one-touch fitting, insert the tube to the end so that it is not pulled off.
■Wiring Connection •Make connection after turning the power off. •Use a separate route when installing wire. Malfunction stemming from noise may occur if wire is installed in the same route as that of power or high-voltage cable. •Be sure to ground terminal FG when using a switching regulator obtained on the market. If analog output is performed connecting to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met.
