2006-12-195011628704-DBE4http://www.delta.com.tw/industrialautomation/Series Temperature ControllerInstruction SheetThank you very much for purchasing DELTA B Series. Please read this instruction sheet before using your B series toensure proper operation and please keep this instruction sheet handy for quick reference.PrecautionsDANGER! Caution! Electric Shock!Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock.1.Make sure power is disconnected while checking the unit inside.2.The symbolindicates that this Delta B Series Temperature Controller is protected throughout by DOUBLE3.INSULATION or REINFORCED INSULATION (equivalent to Class II of IEC 536).WARNING!This controller is an open-type temperature controller. Make sure to evaluate any dangerous application in whicha serious human injury or serious property damage may occur.Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 7.0mm (6.0mm for1.DTB 4824), hole diameter 3.2mm). Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Screw size for DTB4824: M3x 4.5 (With 6.0 x 6.0 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire:2Solid/twisted wire of 2 mm, 12AWG to 24AWG. Please be sure to tighten them properly.Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning.2.Never modify or disassemble the controller.3.Do not connect anything to the “No used” terminals.4.Make sure all wires are connected to the correct polarity of terminals.5.Do not install and/or use the controller in places subject to:6.•Dust or corrosive gases and liquid.•High humidity and high radiation.•Vibration and shock.•High voltage and high frequencyMust turn power off when wiring and changing a temperature sensor.7.Be sure to use compensating wires that match the thermocouple types when extending or connecting the8.thermocouple wires.Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD).9.Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and10.please route power wires as far as possible from load wires to prevent interference and induced noise.This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping11.water, corrosive materials, airborne dust and electric shock or vibration.Please make sure power cables and signals from instruments are all installed properly before energizing the controller,12.otherwise serious damage may occur.Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an13.electric shock.Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any14.internal circuit within this period.Do not use acid or alkaline liquids for cleaning.

Except for the thermocouple B, S, R type, the decimal point positions of allthe other thermocouple type input sensors can be set.The default range of analog input is -999 ~ 9999. For example, when a 0 ~ 20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and9999 indicates 20mA. If change the input range to 0 ~ 2000, then 0 indicates 0mA and 2000 indicates 20mA. One display scale is equal to 0.01mA.OperationThere are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets intothe operation mode. Press thekey to switch to regulation mode. If thekey is pressed for more than 3 seconds,controller will switch to the initial setting mode. Pressing thekey while in the regulation mode or initial setting mode,forces the controller to return to the operation mode. PV/SV: Sets the temperature set point and displays the temperatureprocess value. Usekeys to set the temperature set point.Setting method: While in any function mode, press thekey to select the desired function and use thekeys tochange settings. Presskey to save the changes.

InDead bandDTB series, heating and cooling can be operated simultaneously(Dual Loop output control) to perform temperature control. When DualHeating hysteresisCooling hysteresisLoop output control are used, two control outputs must be connectedONto the heating and cooling devices.

Thisparameter sets an area in which the heating and cooling controloutput is 0 centering around the set point in a Dual Loop outputcontrol mode.: Settings lock. To avoid incorrect operation, two key lock functions are provided.: Lock 1 can lock allsettings. All parameters and temperature settings can be locked to disable changes.: Lock 2 can lock settingsexcept the SV (Set point) value. All parameters and temperature settings can be locked with the exception of the SV value.Pressandkey simultaneously, the “Lock” status can be released.Alarm OutputsThere are up to three groups of alarm outputs and each group allows thirteen alarm types in the initial setting mode.
