No. ZK2-OM00201
Operating environment
- Do not use in an environment where corrosive gases, chemicals, sea water, water or steam are present.
These may cause failure or malfunction.
- Do not use the product in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, even for a
short time, the solenoid valve or pressure switch/sensor may be adversely affected (damage, malfunction, or hardening of
the lead wires).
- Do not use in an area where surges are generated.
When there are machines or equipment that generate large surge near the pressure switch/sensor (magnetic type lifter, high
frequency inductive furnace, motor, etc.), this can result in deterioration and damage of the internal elements. Take measures
against the surge sources, and prevent the lines from coming into close contact.
- Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is directly driven, use the product with a surge absorbing element
built-in.
- The product is CE marked, but not immune to lightning strikes, so take measures against lightning strikes. Be aware of
excessive surrounding noise.
The product is CE marked and has passed the EMC test, but excessive noises in the surrounding area may affect the
functioning of the product.
- Mount the product in a location that is not affected by vibration or impact.
It will cause failure or malfunction.
- Do not let foreign matter, such as wire debris, get inside the product.
In order to avoid failure and malfunction, do not let foreign matter, such as wire debris, get inside the product.
- Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
- Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, protect the product from the sunlight.
Failure or malfunction may occur.
- Keep within the specified operating fluid and ambient temperature range.
Operation under low temperature may lead to damage or operation failure due to frozen moisture in the fluid or air.
Protection against freezing is necessary. Mounting of an air dryer is recommended for elimination of drainage and water.
Avoid abrupt temperature changes even within the specified temperature range.
- Do not use in a location where the product is exposed to radiant heat from surrounding heat sources.
Insufficient air quality may cause operation failure.
Adjustment and Operation
- Connect a load before turning the power supply on.
If the power supply is turned on with no load, over current may flow, causing the pressure switch/sensor to break instantly.
- Do not short-circuit the load.
An error is displayed when the load of the pressure switch/sensor is short circuited, but over current may flow, causing
damage to the pressure switch.
- Do not press the setting buttons with a sharp pointed object.
This may damage the setting buttons.
- If using the product to detect very small pressures, warm up the product for 10 to 15 minutes first.
There will be a drift on the display of approximately 1% for 10 minutes after the power supply is turned on.
- Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
For details of each setting, refer to the Operation Manual of the pressure switch/sensor.
- Do not touch the LED during operation.
The display can vary due to static electricity.
