Note: 1. When using the heater burnout alarm function with a standard model, the linear output board cannot be used for the control
outputs (heat).
2. The Process Controller provides transfer outputs at 4 to 20 mA for the PV and other values and control outputs at 4 to 20 mA
for the current outputs.

Operation
Note: Before changing any switch settings, always turn OFF the power supply to the Process Controller

SETTINGS
1. On a standard model, set up the output boards for control
outputs 1 and 2 before mounting the Controller.
2. On a position-proportional model, the relay output board is
already set, so this setup operation is unnecessary. (Do not
replace with other output boards.)
3. When setting up the output boards, remove the internal
mechanism from the housing and insert the output boards
into the sockets for control outputs 1 and 2.
Setting Up the Output Board
Removing the Output Board
To replace the output board, use a flat-blade screwdriver to push
up the output board.
Setting Up the Option Board
E5AK-T
1. Remove the power board and option boards in the order
shown in the following diagram.
2. Insert the option boards into the sockets for options 1 to 3.
The following diagram shows the relationship between the
option boards and mounting positions.
3. Mount the option boards and the power board in the
order shown.

E5AK-T/E5EK-T E5AK-T/E5EK-T
E5EK-T
1. Remove the power board and option boards in the order
shown in the following diagram.
2. Insert the option board into the socket for option 1. The fol-
lowing diagram shows the relationship between the option
board and mounting position.
3. Mount the option board and the power board in the order
shown.
Removing the Internal Mechanism
To remove the internal mechanism from the housing, use a
Phillips screwdriver matching the screw on the lower part of the
front panel.
1. Turn the screw counterclockwise while pressing the hook on
the upper part of the front panel.
Hook
2. Carefully pull out the internal mechanism while holding the
left and right sides of the front panel.
Mounting
1. Insert the E5AK-T Controller into the panel’s mounting hole
at the position shown in the figure below.
2. Fit the mounting bracket (accessory) into the fixing slots on
the top and bottom of the rear case.
3. Tighten the mounting bracket screws on the upper and lower
parts of the E5AK-T in small increments alternately and
equally until the ratchet starts to slide.

WIRING PRECAUTIONS
•Use ducts to separate input leads and power lines in order to protect the Controller and its lines from external noise.
•Solderless terminals are recommended when wiring the Controller.
•Tighten the terminal screws using a torque no greater than 0.78 N  m, or 8 kgf  cm max. Be careful not to tighten the terminal
screws too tightly.

E5AK-T WIRING
In the following wiring diagrams, the left side of the terminal numbers indicate the inside of the Controller.
Power Supply
Input 100 to 240 VAC or AC/DC 24 V to terminal numbers 9 and 10 according to the specifications.
Sensor Input
Connect the sensor input to terminal numbers 11 to 14 and 33 as follows according to the input type.
Control Output
Terminal numbers 7 and 8 are for control output 1 (OUT1), and terminal numbers 5 and 6 are for control output 2 (OUT2). The following
diagrams show the available output boards and their internal equalizing circuits.
With E53-V  output boards, approx. 2 V is output for one second after the power is interrupted.
