Digital Temperature Controller, Enclosure Type , Accessories For Dry Type Transformer

 

1 Type and Classification of Function

TypeFunction

Type D
(Ordinary type)

Three-phase circular measurement; Three-phase circular display/maximum value display and mutual switching between two functions; Input disconnection and trouble self-check display and output; Auto start and stop of cooling fan and output; Over-temperature alarm display and output; Over-temperature tripping display and output; Display of manual/auto modes of fan, output and mutual switching; Digital compensation for value displayed in each channel; Function of "black box"; Timed start, stop and control function of fan; Detection of output status.
Type EThe same as Type D, with addition of 4~20mA analogue current output.
Type FThe same as Type D, with addition of RS485 serial communications function.
Type GThe same as Type D, with addition of one-way transformer room temperature measurement and control.
Type IThe same as Type D, with addition of one-way transformer core temperature measurement and alarm.
Type LThe same as Type D, with addition of protection and alarm function for lack of phase and failure of fan.
Type C

The same as Type D, with addition of interlock control of Pt100
and PTC on over-temp alarm and over-temp trip signal.

 
Note: Other special requirements for the temperature controller should be indicated when placing orders.

2. Sensing Cable Assembly

1 ) D25 sensing cable (3-wire system), cable length tolerances: ±2.5%
Note: Correspondence between line color and phase:
 
Yellow corresponds phase A; Green corresponds phase B;
Red corresponds phase C; Blue corresponds d-way.

Types G/I 4-way cable connection schematic diagram
 
2)  Sensor
 
2.1 Pt100 platinum resistor is a thermo-resistor with better linearity in the range of -30.0℃~240.0℃ and meets the requirements for Grade B set forth in GB/T8622-97--Technical Specification and Reference Table for Industrial Platinum Resistance.
2.2 Overall dimension: Ф4mm×40mm
2.3 Corresponding curves to the resistance and temperature of Pt100 platinum resistor:
 
3) Humidity module (Selection function)
 
3.1 Electrical parameters
3.1.1 Temperature range: 0.0℃~70.0℃
3.1.2 Humidity range: 0.0%RH~100.0%RH (Can be condensed)
3.1.3 Detection range: 0.0%RH~99.0%RH
3.1.4 Save temperature range: -20.0℃~85.0℃
3.1.5 Save humidity range: Below 95% RH (Can be condensed)
3.1.6 Humidity detection accuracy: ±5%RH (Conditions: at 25℃, 60%RH)
3.2 Corresponding curves to the input moisture percentage and output voltage:
 
4) Interlock control of Pt100 and PTC on over-temp alarm and over-temp trip signal
 
4.1 Explanation of PTC (Selection function)
PTC is an abbreviation for positive temperature coefficient thermistor, which is a semiconductor resistor having a typical temperature sensitivity. When the temperature exceeds a certain value (Fixed temperature point not be adjustable), its resistance value will increase impulsively with increasing temperature, i.e., resistance mutation.
 
4.2 Logical relation of interlock control of Pt100 and PTC
4.2.1 Interlock control of Pt100 and PTC on over-temp alarm
4.2.1.1 When the temperature measured by Pt100 exceeds over-temp alarm value, in addition, PTC reaches the point of over-temp alarm and the resistance has mutated. Over-temp alarm signal will output in 6 seconds.
4.2.1.2 When the temperature measured by Pt100 exceeds over-temp alarm value, in addition, PTC has went wrong (Short circuit or open circuit, see table ‘PTC Status Inquiry’ below). Over-temp alarm signal will output in 6 seconds.
4.2.1.3 When PTC reaches the point of over-temp alarm and the resistance has mutated, in addition, all Pt100s have went wrong (Displaying ‘-OL-’ or ‘-OP-’ or ‘ -OH-’). Over-temp alarm signal will output in 6 seconds.
4.2.2 Interlock control of Pt100 and PTC on over-temp trip
4.2.2.1 When the temperature measured by Pt100 exceeds over-temp trip value, in addition, PTC reaches the point of over-temp trip and the resistance has mutated. Over-temp trip signal will output in 10 seconds.
4.2.2.2 When the temperature measured by Pt100 exceeds over-temp trip value, in addition, PTC has went wrong (Short circuit or open circuit, see table ‘PTC Status Inquiry’ below). Over-temp trip signal will output in 10 seconds.
4.2.2.3 When PTC reaches the point of over-temp trip and the resistance has mutated, in addition, all Pt100s have went wrong (Displaying ‘-OL-’ or ‘-OP-’ or ‘-OH-’). Over-temp trip signal will output in 10 seconds.

4.4.4 About PTC ordering
4.4.4.1 Two options
4.4.4.1.1 PTCAL&PTCAH: Involved in controlling over-temp alarm and over-temp trip signal output
4.4.4.1.2 PTCAH: Only involved in controlling over-temp trip signal output.
4.4.4.2 We offer PTCAL and PTCAH whose temperature point is as same as the controller setting for over-temp alarm and over-temp trip. Over-temp alarm PTC is PTC130, over-temp trip PTC is PTC150. PTC temperature point of resistance mutation is fixed value could not be adjustable. If users need to change the PTC temperature point, please make a note when ordering.
