Aut
Auxiliary output
type
Define AUX only when AUX is worked as the auxiliary output of a heating/refrigerating
bidirectional systerm.
SSr: to output SSr driver voltage or thyristor zero crossing trigger signal. G or K1
module should be installed. The output power can be adjusted by adjusting the
on-off time proportion. The period (CtI) is generally 0.5
～
4 seconds.
rELy: for relay contact output or for execution system with mechanical contact switch.
To protect the mechanical switch, the output period (CtI) is limited to 3
～
120 seconds,
and generally is 1/5 to 1/10 of derivative time.
0-20: 0
～
20mA linear current output. X3 or X5 module should be installed in AUX
slot.
4-20: 4
～
20mA linear current output. X3 or X5 module should be installed in AUX
slot. (Not applicable for heating/refrigerating bidirectional control.)
Note: In a heating/refrigerating bidirectional control system, if any of OPt or Aut is set
to rELy, then CtI is limited to 3
～
120.

-1
～
-110%: The instrument works for a bidirectional system, and has
heating/refrigerating dual output. When ACt=rE or rEbA, OUTP (main output) works
for heating, and AUX (Auxiliary output) works for refrigerating. When Act=dr or drbA,
