4 DTY-EPU Thank you very much for purchasing the EP Monitor DTY-EPU. Please read this Owner s Manual carefully and thoroughly for the correct and optimum use of the EP Monitor. Kindly keep this manual in a convenient place for quick reference. Specifications EP Monitor Model Item Voltage Current Number of inputs Sensor input Voltage range Maximum applied Number of outputs Method Switch output Applied Current Voltage drop Electric potential Switch output check Input channel check key switch Communication I/F Operating temperature range Operating humidity range Storage temperature range Case material Outer dimensions Mass Accessories Notes:. At EP Sensor in unconnected state. When in the ion balance monitor mode, the unit is V (no decimal point). General Precautions Wiring. When using a switching regulator obtained on the market for the power supply, always ground the frame ground (F.G.) terminal.. When using equipment (switching regulator, inverter motor, etc.) that can become a source of noise around the EP Sensor mounting area, always ground the equipment frame ground (F.G.) terminal.. When wiring is completed, check that there is no error in the wiring connections.. Although this monitor can monitor the conditions of up to EP Sensors at the same time, the EP Sensor settings are performed unit at a time. This is performed by connecting the communication cable for each EP Sensor to be set. Others. Check power supply fluctuations to ensure that power input does not exceed the rated value.. Avoid use during the transient period (0.s) when the power is switched on.. Do not use needle tips or other sharp points to perform key. Mounting Sensor and connector connection procedure Connect the EP Sensor DTY-EPS and the mini clamp connector. Follow the procedure below to perform the connections.. Check that the connector cover (the part where lead wires are to be inserted) is protruding from the connector body. It cannot be used if it s flat and placed at the same level against the body. u EP Monitor (Dedicated for EP Sensor) Owner s Manual Ver..0 This product is intended for detection of targeted objects, and does not have control functions for the purposes of accident prevention or other safety measures.

Arrange the EP Sensor cable into the required form. Since the insulation on the tips of the lead wires have been peeled off and soldered, cut the wires at about 0mm [0.in.] from the tips so that they do not protrude from the insulation. Cut Caution Ground terminal Caution: Handle any unused lead wires so that they will not short circuit.. Follow the instructions in the table to insert the lead wires into the hole in the connector cover. Look through the top of the semi-transparent cover to check that the lead wires have been firmly inserted all the way to the back. (Insertion is about mm [0.in.].) Use caution in making the connections, since switching on the power with mistakes in the connections will damage the EP Sensor and EP Monitor.

Taking care to avoid letting the lead wires slip out from the connector, use pliers or some other hand tool to crimp the cover and connector body, and push the cover into the connector body. Limit the crimping force to 0.N [0lbf.]. When the cover is flat and placed at the same level against the connector body, the connection is complete.. Check one more time that the wiring is correct.

Electric potential unit for ion balance monitor mode: V, for other modes: kv. When the kv is used, it becomes a decimal point. The electric potential of the selected channel is indicated in the LED. (The selected channel s A.S.OUT LED (green) lights up. See Figure.) The SW.OUT LED (red) lights up when the switch output is turned ON. Pressing the key or key changes the selected channel. When in auto switch, pressing the,, or key returns the to the electric potential at fixed channel. If appears, it means that the selected channel s EP Sensor was not connected or has a wire break. In the case of a wire break, shut off the power and replace the EP Sensor. EP Monitor s Caution. Since miswiring in the EP Sensor, or in the power supply, switch, and communication cable, can damage both the EP Monitor and EP Sensor, always check the wiring before switching on the power.. The setting conditions are written to EEPROM and saved. Be aware that EEPROM has a finite lifetime, with a write guarantee times up to 00,000 times. preparation Connect the connector to the EP Sensor cable.
