Wiring Hooku
The two-wire connection is sim lest method, but does not com ensate for
lead-wire tem erature change and often requires calibration to cancel lead-wire
resistance offset.
The three-wire connection works best with RTD leads closely equal in
resistance. The device measures the RTD, lus u er and lower lead dro
voltage and the subtracts twice the measured dro in the lower su ly current
lead roducing excellent lead-resistance cancellation for balanced
measurements.
The four-wire RTD hooku is a licable to unbalanced lead resistance and
enables the device to measure and subtract the lead voltage, which roduces
the best lead-resistance cancellation.
When configuring your controller, select RTD ty e and RTD value in the
In ut Ty e menu (see Part 3).
If the in ut wires of the meter get disconnected or broken, it will dis lay
+OPN “In ut (+) O en” message exce t in case of 500/1000 Ω 2-wire
RTD. In this case the dis lay shows -OPN “In ut (-) O en” message. For
safety ur ose you may want to set u your alarm to be triggered when
in ut is o en. See Alarm 1 & 2 cha ters for details.

Excitation is not available if communication o tion is installed.
This device has snubber circuits designed to rotect the contacts of the
mechanical relays when it switches to inductive loads (i.e. solenoids,
relays). These snubbers are internally connected between the Common
(C) and Normally O en (NO) relay contacts of Out ut 1 and Out ut 2.
If you have an inductive load connected between Common (C) and
Normally Closed (NC) contacts of the mechanical relays and you want to
rotect them from the rush current during the switching eriod, you have
to connect an external snubber circuit between Common (C) and
Normally Closed (NC) contacts as indicated in the figure below.
