※ Method for correcting retransmission output
In the retransmission output mode, process value (PV), set value (SV),
manipulated variable(MV) or sensor power supply (SPS) may be chosen, and the
output will be generated in direct current of 4~20mA. (SPS is DC15V/25mA)
When retransmitting output (4 to 20 mA) is used, tolerance may occur due to the conversion resistance and
peripheral equipment error. When necessary, you can easily perform high-precision calibration as described below.
① If the retransmission output upper limit (RET.H) is set to 100.0 and the lower limit (RET.L) is set to 0.0.
② Change RET to SV transfer mode, change the SV as the current RET.H (100.0) value, check the transferred
value of the recorder or receiver (ex. 99.6) next note that the RET. L (0.0) value is also changed by transferring
the SV(ex. 0.3). (This must be the same as the setting on the receiving side input range.)
③ Change the transmitted value upper limit (RET.H) to 99.6, and change the transmission output lower limit
(RET.L) to 0.3.
④ When the retransmission output mode (RET) is changed back to the PV retransmission output mode, the
correction is completed.
When the low limit alarm is used, when the power is turned on and the
temperature rises, unnecessary low limit alarm occurs during the rise. When
the hold function is enabled, the low alarm can be ignored until the alarm set
value is released once the initial power is turned on.
