Notice 3. Installing the Controller Never place the controller directly on flammable items. If the controller has to be installed close to flammable items or equipment, be sure to enclose the controller in shielding panels positioned at least 150mm away from each side. These panels should be made of either 1.43mm thick metal-plated steel plates or 1.6mm thick uncoated steel plates. q Mount the controller at an angle within 30° from horizontal with the screen facing upward.

Panel Cutout Dimensions and External Dimensions 5. Wiring 6. Hardware Specifications CAUTION 1) Before you start wiring, turn off the power source and use a tester to check that the controller and cables are not receiving any power in order to prevent electric shock. 2) For safety, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC60947) near the controller so as to be operated easily, and clearly indicate that the device is used to de- energize the controller. 3) Wiring should be carried out by personnel with appropriate electrical knowledge and experience. NOTE 1) Use a single-phase power source. If the source has a lot of noise, use an isolation transformer for the primary side and a line filter (we recommend TDK’s ZAC2205-00U product) for the secondary side. When this noise-prevention measure is taken, keep the primary and secondary power cables well apart. Since the controller has no fuse, be sure to install a circuit breaker switch (of 5A and 100V AC or 220V AC, and that conforms to IEC standards) and clearly indicate that the device is used to de-energize the controller. 2) For thermocouple input, use shielded compensating lead wires. For RTD input, use shielded wires which have low resistance and no resistance difference between the 3 wires. See the table given later for the specifications of the cables and terminals and the recommended products. 3) The control output relay cannot be replaced even though it has a limited service life (100,000 relay contacts for the resistance load). Thus, an auxiliary relay should be used so that the load can be turned on and off. 4) When using an inductive load (L) such as an auxiliary relay and solenoid valve, be sure to insert a CR filter (for AC) or diode (for DC) in parallel as a spark-rejecting surge suppressor to prevent malfunctions or damage to the relay. 5) When there is the possibility of being struck by external lightning surge, use the arrester to protect the instrument. NOTE Always fix a terminal cover bracket to the UT150L limit controller before wiring if an optional anti-electric- shock terminal cover (part number: L4000FB) is used. 7.

(The functions described in other sections of this manual and the general functions are not discussed.) Parameter Function Relay hysteresis for control output HYS PV input bias BS For control, you can set a hysteresis around the on/off point (SP) to prevent chattering. PV input filter FL On/off point (SP) ON OFF Hysteresis This function should be used when the PV display value may fluctuate greatly, for example, when the measured input signal contains noise. The filter is of the first-order lag type, and FL sets the time constant. If a larger time constant is set, the filter can remove more noise. Input 2-seconds filter 10-seconds filter This function adds a bias value to the measured input value, and the result is used for display and control computation. PV value inside the controller =measured input value + PV input bias This function is useful for carrying out fine adjustment when the PV value is within the required accuracy but it differs from the value obtained by other equipment. Decimal point position For DC voltage input, the input signal can be scaled for the particular engineering unit. For example, if you set the of measured input input type (IN) at range code 22, the initial range is 0.0 to 100.0. a. Using DP, set the decimal point position fit for the engineering unit you want to use. (In the example below, the 2 DP digits to the right of the decimal point) b. Next, register the scale values of the measured input scale using RH and RL. (In the example below, RH=10.00 Maximum/minimum and RL=0.00) value of measured input range (scale) 0.0 (1V) Initial scale 100.0 (5V) RH, RLMeasured input scale 0.00 (RL) (after being scaled) 10.00 (RH) Register the decimal point position using DP. Maximum/minimum Using the SPH and SPL parameters, you can limit the setting range of the target setpoint (SP) within the measured value of target setpoint input range (scale). range This function prevents SP from being mistakenly set at too large or too small a value (beyond the setting range). SPH, SPL 8. Limit Control Function s Limit Control When a measured value (PV) exceeds a setpoint (SP), “EXCEEDED” lamp lights, and “OUT” lamp turns ON (A). The limit output relay is de-ener- gized then. “EXCEEDED” lamp turns off when PV goes into normal condition, while the output (OUT) display lamp stays on as it is (B). The output (OUT) display lamp turns off when a confirming operation is done by an operator (C). The way to con- firm is pressing the “ ” key (or by an external contact, according to the setting of setup parameter DIS). The confirming operation is not accepted during PV exceeds SP (D) (during EXCEEDED lamp lights*). State of output relay is de-energized whenever “OUT” lamp is on. * Check the “HYS” value if the EXCEEDED lamp is not turn off when PV is lower than SP. NOTE The confirming operation cannot be done by communication (RS-485). s Confirming Operation Do the confirming operation when you start limit con- trol. This operation must be necessary every time when the controller is powered on. By the confirming opera- tion, state of output relay is energized and the output (OUT) display lamp turns off, if the PV does not exceed SP.s Power On Status The state of output relay at power -on can be set by a setup parameter restart mode "R.MD". (1) When "R.MD" is set to 0. The output relay is always de-energized (opened) at power-on, even if PV does not exceed SP (A). The output (OUT) display lamp is lit. After the confirming operation, state of output relay is energized (closed) and the output (OUT) display lamp turns off if the PV does not exceed SP (B).

Step 2: Press the key for at least 1 second to turn off the output (OUT) display lamp. The confirming operation is now finished. Note 1: The output (OUT) display lamp does not turn off during the EXCEEDED lamp lights. Note 2: Check the “HYS” value if the EXCEEDED lamp is not turn off when PV is lower than SP.

It is displayed in the “TIME” in the confirma- tion display ➀. Display time range: 00.00 to 99.59 q How to RESET • Push the “ ” key for about one second to reset the duration time in the confirmation display ➀ where “TIME” is displayed. When the count is reset, “0.00” is displayed until PV exceeds SP again. • The time count is reset when power is turned on. • If PV exceeds SP while the old time count data is retained in the memory, the old data should be automatically reset, and the new time counting starts from “0.0”. • It is impossible to reset the time count while PV exceeds SP by any operation. • Duration time cannot be reset by an external contact or communication (RS-485). s Maximum/Minimum Value The maximum value or minimum value of PV is stored in the memory and displayed in the “HI” or “LO” display in the confirmation display ➁. When the control type is specified as high limit control, the maximum value is displayed in the “HI” display, and the control type is specified as low limit control, the minimum value is displayed in the “LO” display. When the PV exceeds SP and then return to the normal status, Maximum/Minimum value is retained as it is, but when PV exceeds SP again, it is automatically reset and start taking new value for its maximum/minimum value. q How to RESET • Push the “ ” key for about one second to reset the maximum/minimum value in the confirmation display ➁ where “HI” or “LO” is displayed. The value is reset, and the value immediately after the confirmation should be recognized as a maximum or minimum value. • When the power is turned-on, the memory should be reset and the first PV should be recognized as maximum. • Maximum/minimum value cannot be reset by an external contact or communication (RS-485). • It is impossible to reset the maximum/minimum value while PV exceeds SP by any operation. 9.
