PARAMETER DESCRIPTION

*

x

refers to channel number, can be 1~2, 1~4, 1~6 for AI-702M, 704M and 706M respectively.

Setting range

H.ALx

High limit alarm

x channel high alarm on when PVx (the present value of x
channel)>H.ALx;
Alarm releases when PVx<H.AL - dFx.
Set H.ALx maximum value will disable function

-1999~+9999

★

or

defined unit

L.ALx

Low limit alarm

x channel low alarm on when PVx<L.ALx;
Alarm releases when PVx>L.ALx + dfx.
Set L.ALx minimum value will disable function

dFx

Dead band

dF is set to avoid high frequent alarm on/off actions
caused by process input fluctuation.

Note: Input spec. should be compatible with input module.
For  those  spec.  unknown,  use  J1  for  thermocouple  and
mV  inputs,  J2  for  two-wire  RTD,  and  J0  for  three-wire
RTD.

Multiplication: set

Sn3=40, PV3=PV1 x PV2 (PV refer to

input value)
Summation: set Sn3, Sn4, or Sn5 =41, its input is the sum
of the inputs of previous channels, e.g. when Sn5=41,
PV5=PV1+PV2+PV3+PV4.
Subtraction: set Sn3=42, PV3=PV2-PV1
