B Series Temperature Controller User Manual 1 Precaution DANGER! Caution! Electric Shock! 1. Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock. 2. Make sure power is disconnected while checking the unit inside. 3. The symbol indicates that this Delta B Series Temperature Controller is protected throughout by DOUBLE INSULATION or REINFORCED INSULATION (equivalent to Class II of IEC 536). WARNING! This controller is an open-type temperature controller.

Operation 6 There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into the operation mode. Press the key to switch to regulation mode. If the mode. Pressing the key is pressed for more than 3 seconds, controller will switch to the initial setting key 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 temperature process value.
Display and adjust output value of 1st output group (Display in PID control mode and manual RUN mode) Time setting for valve from full close to full open. (Display when valve control is ON) Press ASCII, RTU communication format selection Press Press Display and adjust output value of 2nd output group (Display in dual loop PID control mode and manual RUN mode) Press Valve Dead Band setting. (Display when valve control is ON) Press Upper-limit regulation of valve output with feedback to controller.
Dual Loop Output Control (Heating / Cooling Control) 7 Dead band Temperature control can be achieved either by heating or cooling. In DTB series, heating and cooling can be operated simultaneously (Dual Loop output control) to perform temperature Cooling hysteresis control. When Dual Loop output control are used, two control outputs must be connected to the Heating hysteresis ON heating and cooling devices.
8 Alarm Outputs There are up to three groups of alarm outputs and each group allows thirteen alarm types in the initial setting mode. The alarm output is activated whenever the process temperature value (PV) is getting higher or lower than the set point of alarm limit.
9 Current Transformer (CT) Function The Current Transformer (CT) function is used with the alarm output. When using a current transformer (CT) with the controller, change the corresponding alarm output mode to mode 13 (alarm output set value is 13), then turn to operation mode and set the current lower-limit and current upper-limit. You can set current alarm range between 0.5A ~ 30A, display resolution is 0.1A and measure accuracy is +/- 0.5A.

Mounting 16 Mounting Method Mounting Bracket Installation Step 1 : Insert the controller through the panel cutout. Step 2 : Insert the mounting bracket into the mounting groove at the top and bottom of the controller Step 3 : Push the mounting bracket forward until the bracket stops at panel wall. Step 4 : Insert and tighten screws on bracket to secure the controller in place. (The screw torque should be 0.8kgf-cm to 1.
