oP02: Heater resistance setting

[oP02: Heater resistance setting] in OPTION mode of the display panel is used to record the

initial heater resistance. Set it with the following procedure.

Step 1:

Complete the settings specified in the previous section.

Step 2:

Continue operation until the heater temperature becomes stable.

※

Disconnection may not be detected correctly if the following steps are

executed before the heater temperature becomes stable.

Step 3:

Select [oP02: Heater resistance setting] on the display panel.

Step 4:

Press the DOWN key on the setting screen. [SEt] flashes on the 7-segment

LED.

Step 5:

Press the SAVE key. If the heater resistance is within the settable range, [ESc]

is displayed.

※

The initial value can be set only when it is 25% of the rated voltage

and the rated current or higher. If the value is outside the range, the

LED continues to flash while displaying [SEt] even when the SAVE key

is pressed.

Heater disconnection detection (highly functional version)

(1)

Divide the number of heaters by two so that A is equal to B or B + 1.

(2)

The number of heaters connected to the A side and the B side are memorized by the unit.

(3)

The load current of the A side is obtained via the main circuit CT, external CT, and

conversion board.

(4)

The load current of A + B is obtained via the built-in CT.

(5)

The current ratio (balance) of the heaters divided into two is obtained using these load

currents.

(6)

The current ratio (balance) of the heaters is periodically obtained.

(7)

When the current ratio of the heaters deviates from the theoretical current ratio value

calculated from the preset number of connected heaters, the error code is displayed and

the external warning relay signal specified with [F6: Error output destination selection] is

output. The unit continues operation, instead of stopping.

(8)

For malfunction prevention, the heater disconnection detection is not performed when the

load current of heater A + heater B is less than 10% of the rated current.

(9)

For false detection prevention, the heater disconnection detection is not performed for 5

minutes after the start of operation.
