  4. use the specified size of crimp terminals (m3.5 screws) to wire the terminal block. t ighten the screws on the terminal block using the tightening torque within the range of 1.2 n.m. 5. do not connect anything to unused terminals. emc guidelines: 1. use proper input power cables with shortest connections and twisted type. 2. layout of connecting cables shall be away from any internal emi source. all safety related codifications, symbols and instructions that appear in this operating manual or on the equipment must be strictly followed to ensure the safety of the operating personnel as well as the instrument. if the equipment is not handled in a manner specified by the manufacturer it might impair the protection provided by the equipment. read complete instructions prior to installation and operation of the unit. w arning: risk of electric shock. load connections 1. the service life of the output relays depends on the switching capacity and switching conditions. consider the actual application conditions and use the product within the rated load and electrical service life. 2. although the relay output is rated at 10 amps it is always necessary to use an interposing relay or contactor that will switch the load. this avoids damage to the controller in the event of a fault short developing on the power output circuit. 3. always use a separate fused supply for the power load circuit and do not take this from the live and neutral terminals supplying power to the controller . 3. circuit breaker or mains switch must be installed between power source and supply terminals to facilitate power 'on' or off  function. however this switch or breaker must be installed in a convenient position normally accessible to the operator . 4. use and store the temperature controller within the specified ambient temperature and humidity ranges as mentioned in this manual. wiring guidelines w arning: 1. t o p r e v e n t t h e r i s k o f e l e c t r i c s h o c k p o w e r s u p p l y t o t h e e q u i p m e n t m u s t b e k e p t o f f w h i l e d o i n g t h e w i r i n g a r r a n g e m e n t . d o n o t t o u c h t h e t e r m i n a l s w h i l e p o w e r i s b e i n g s u p p l i e d . 2. t o eliminate electromagnetic interference use short wire with adequate ratings; twists of the same in equal size shall be made. for the input and output signal lines, be sure to use shielded wires and keep them away from each other . 3. cable used for connection to power source, must have a 2 cross section of 1mm or greater . these wires shall have insulation capacity made of at least 1.5kv . 4. when extending the thermocouple lead wires, always use thermocouple compensation wires for wiring. for the r td type, use a wiring material with a small lead resistance (5 ? max per line) and no resistance dif ferentials among three wires. 5. a better anti-noise ef fect can be expected by using standard power supply cable for the instrument. maintenance 1 the equipment should be cleaned regularly to avoid blockage of ventilating parts. 2. clean the equipment with a clean soft cloth . do not use isopropyl alcohol or any other cleaning agent. 1. when powering up for the first time, disconnect the output connections. 2. fuse protection: the unit is normally supplied without a power switch and fuses. make wiring so that the fuse is placed between the mains power supply switch and the controller . (2 pole breaker fuse- rating: 275v ac,1a for electrical circuitry is highly recommended) 3. since this is a built-in-type equipment (finds place in main control panel), its output terminals get connected to host equipment. such equipment shall also comply with basic e m i / e m c a n d o t h e r s a f e t y r e q u i r e m e n t s l i k e b s e n 6 1 3 2 6 - 1 a n d b s e n 6 1 0 1 0 r e s p e c t i v e l y . 4. thermal dissipation of equipment is met through ventilation holes provided on chassis of equipment. such ventilation holes shall not be obstructed else it can lead to a safety hazard. 5. the output terminals shall be strictly loaded to the manufacturer specified values/range. electrical precautions during use electrical noise generated by switching of inductive loads can create momentary disruption, erratic display , latch up, data loss or permanent damage to the instrument. t o reduce noise: a) use of snubber circuits across loads as shown above, is recommended. b) use separate shielded wires for inputs. safety precautions inst alla tion guidelines 1. this equipment, being built-in-type, normally becomes a part of main control panel and in such case the terminals do not remain accessible to the end user after installation and internal wiring. 2 do not allow pieces of metal, wire clippings, or fine metallic fillings from installation to enter the product or else it may lead to a safety hazard that may in turn endanger life or cause electrical shock to the operator . 1. prepare the panel cutout with proper dimensions as shown above. 2. remove the clamp from the controller and push the controller into the panel cutout. insert the clamp from the rear side until the main unit is securely fit into the panel. 3. the equipment in its installed state must not come in close proximity to any heating sources, caustic vapors, oils, steam, or other unwanted process by-products. mechanical inst alla tion n l c no tc lo a d r c tc snubber mov tc tc n l snubber c no r c contactor lo ad c mov f o r l o a d c u r r e n t l e s s t h a n 0 . 5 a f o r b i g g e r l o a d s , u s e i n t e r p o s i n g r e l a y / c o n t a c t o r outline dimensions (in mm) panel cutout dimensions (in mm) specifica tions display 3 + 3 digit, 7 segment digital display led indications r: control output on keys 3 keys for digital setting input specifica tions input signal thermocouple (j,k,t ,r,s) / r td (pt100) sampling time 250 ms input filter (ftc) 0.2 to 10.0 sec resolution o fixed 1 resolution t emperature unit o c / f selectable indication accuracy f or tc inputs: 0.25% of fs 1 for r & s inputs: 0.5% of f .s 2 (20 min of warm up time for tc inputs) f or r td inputs : 0.1% of fs 1 functional specifications control method 1) pid control with auto tuning2) on-off control proportional band (p) 1 to 400 integral t ime (i) 0.0 to 99.9 min derivative t ime (d) 0 to 999 sec cycle t ime 0.1 to 99.9 sec hysteresis width 0.1 to 99.9 manual reset v alue -19.9 to 19.9 control output (relay or ssr user selectable) relay contact (spdt) 10 a @ 250v ac / 30v dc, resistive ssr drive output (v oltage pulse) 12v dc, 50 ma power suppl y supply v oltage 85 to 270v ac/dc (ac: 50 or 60 hz ) optional - 24v ac/dc power consumption 5 v a max @230v ac t emperature operating : 0 to 50 c ; storage : -20 to 75 c humidity (non-condensing) 95% rh w eight tc533ax: 129 gmstc233ax: 180 gms tc333ax: 240 gms o p e ra ti n g /1 1 0 3 / t c 5 3 3 a x / t c 2 3 3 a x / t c 3 3 3 a x / o p 2 9 3 -v 0 4 (p a g e 1 o f 3 ) a 52 72 96 b 52 72 96 c 94 83.7 73 d 45 67 90.5 e 4 4.5 5 f 46 69 92 g 46 69 92 dim models tc533ax tc333ax tc233ax a b c d e f g e n w terminal connections control output measured v alue input relay output ssr drive output 12 vdc 10 12 + t h e r m o c o u p l e ( j , k , t , r , s ) rtd (pt100) 6 7 tc+ tc c o n n e c t t h e r m o c o u p l e s e n s o r a c c o r d i n g t o p o l a r i t y s h o w n . 6 7 8 rtd1 rtd2 rtd3 pt100 for 2-wire r td input short terminals 7 and 8 nc 3 4 5 no com f o r t c 5 3 3 a x selec tc533ax / tc233ax / tc33 3ax operating instructions r caution 7 8 9 10 6 tc /rtd1 tc /rtd2 rtd3 1 1 12 2 1 3 4 5 l (+) n ( ) no com ssr + - nc - + o p 2 9 3 - v 0 4 free datasheet http:///
