1-4 <1. installation> im 05d01d13-41e 4th edition : may 31, 2006-00 how to install caution turn off the power to the controller before installing it on the panel because there is a possibility of electric shock. after opening the mounting hole on the panel, follow the procedures below to install the controller: 1. insert the controller into the opening from the front of the panel so that the terminal board on the rear is at the far side. 2. set the brackets in place on the top and bottom of the controller as shown in the figure below, then tighten the screws of the brackets. take care not to overtighten them. large bracket (top mounting hardware) terminal board small bracket (bottom mounting hardware) panel insert a screwdriver into the brackets to tighten the screws. direction to insert the controller insert the controller into the opening at the front of the panel. recommended tightening torque :0.4 n m nameplate indicating mac address do not remove the nameplate. the mac address is required for network connection.
<1. installation> 1-5 im 05d01d13-41e 4th edition : may 31, 2006-00 1.3 how to connect wires caution 1) before carrying out wiring, turn off the power to the controller and check that the cables to be connected are not alive with a tester or the like because there is a possi- bility of electric shock. 2) for the protection and safe use of the controller, be sure to place a circuit breaker (conforms with iec60947, 5a, 100v or 220v ac) near the controller where the breaker can easily be operated. in addition, be sure to indicate that it is the instrument to cut the power supply of the controller. 3) wiring must be carried out by personnel who have basic electrical knowledge and practical experience. note 1) provide power from a single-phase instrument power supply. if there is a lot of noise in the power line, insert an insulating transformer into the primary side of the line and use a line filter (recommended part: zac2205-00u from tdk) on the secondary side. as a countermeasures against noise, do not place the primary and secondary power cables close to each other. 2) for thermocouple input, use shielded compensating lead wires for wiring. for rtd input, use shielded wires that have low conductor resistance and cause no significant differences in resistance between the three wires. the cables to be used for wiring, terminal specifications, and recommended parts are as shown below. 3) control output relays may be replaced. however, because they have a life of 100,000 times that of the resistance load, use auxiliary relays to turn on/off a load. 4) the use of inductance (l) loads such as auxiliary relays, motors and solenoid valves causes malfunction or relay failure; always insert a cr filter for use with alternating current or a diode for use with direct current, as a spark-removal surge suppression circuit, into the line in parallel with the load. 5) when there is a possibility of being struck by external lightning surge, use the arrester to protect the instrument. for dc relay wiring for ac relay wiring ut351 ut s contact diode (mount it directly to the relay coil terminal (socket).) relay (use one with a relay coil rating less than the ut s contact rating.) external dc power supply r r ut351 cr filter (mount it directly to the relay coil terminal (socket).) external ac power supply relay (use one with a relay coil rating less than the ut s contact rating.) ut s contact

(alarms with the stand-by feature temporarily return to their stand-by state, however.) setting parameters that have already been configured retain their settings. auto-tuning is cancelled. after recovery from a power failure, control action resumes in the same mode as the one before the occurrence of the power failure. the control output begins with the preset output value. troubleshooting when the controller fails to operate correctly if your control tasks are not successful, check the preset parameters and controller wiring before concluding the controller to be defective. the following show some examples of troubleshooting you should refer to in order to avoid the possibility of other problems. the controller does not show the measured input (pv). the UT351-XA controllers have a universal input. the type of pv input can be set/changed using the parameter in . at this point, the controller must be wired correctly according to the selected type of pv input. check the wiring first if the controller fails to show the correct pv. to do this, refer to 2. initial settings. with the parameters rh , rl , sdp , sh and sl , it is possible to scale the input signal and change its number of decimal places. also check that these parameters are configured correctly. the controller does not provide any control output or the control output does not change at all. the UT351-XA controllers have a universal output. the type of control output can be set/changed using the parameter ot . at this point, the controller must be wired correctly according to the selected type of control output. check the wiring first if the controller provides no control output. to do this, refer to 1.5 terminal wiring diagrams. with the parameters oh and ol , it is possible to set/change the high and low limits of control output. the control output may not change at all, however, because of restrictions on these parameters. also check the restrictions on these parameters. the control output can only be changed when the controller is in the man mode. if the man lamp is off (i.e., the controller is in the auto mode), you cannot change the control output using key operation. the control output does not change soon after the target setpoint (sp) has been changed. if this happens, check the setpoint of the parameter c.md . in cases where fixed- point control is selected as the pid control mode (c.md = 1), tracking based on the i- term works to prevent the control output from changing suddenly even if the target setpoint sp is varied. the control output therefore may appear to be working incorrectly at first; however it gradually adapts itself to the new target setpoint.
