at the specified rating.

NOTES:

1) To avoid shock and possible instrument damage,
connect power last.

2) For power connections use 16 AWG or larger wires
rated for 75 °C.

3) Use copper conductors only.

4) Do not run input wires with power cables.

C.2) Inductive Loads

High voltage transients may occur when switching induc­tive loads. Through internal contacts these transients
may introduce disturbances which can affect the perfor­mance of the instrument. The same problem may occur
when a switch is used in series with the internal contacts
as shown below.

C

R

POWER

LINE

LOAD

For all the outputs, the internal protection (varistor)
assures protection up to 0.5 Amp on inductive loads.

It is good electrical practice to install an additional RC net­work across and as close to the external contacts as
possible.

Control Output Function

The relay output operates in fail-safe mode (relay de­energized during reset condition) and latching mode.

The control output turns OFF when the setpoint is ex­ceeded when C1 = Hi, or C1 = Lo. (When C1 = Hi.Lo
control output turns off when the process is greater than
“Su” or less than “S1”).

The control output remains OFF until the process is
within setpoint and the acknowledge action has been
performed (the sequence of action may or may not be
important depending on parameter C2).

The upper display flashes when the setpoint is exceeded
and returns to a steady display when the process is within
setpoint.

When the control output is OFF the RESET LED is ON
(if C2 = 0) or flashes (if C2 = 1).

When C2 = 1 the RESET LED is steady ON when control
output is OFF and acknowledged.

The reset condition can be stored in permanent memory
(see C4).

Acknowledgment can be performed by pressing the
RESET key, by momentarily closing the external dry
contact or by a command from the serial link.

The length of the reset condition and max/min values
detected are stored in memory and available for viewing
until the next reset condition occurs. The information is
lost at power down.

During a reset condition the values are continuously
updated and can be monitored.

CALIBRATION PROCEDURE

Calibration parameters are logically divided into groups
of two parameters each – initial scale value and final
scale value. A calibration check is provided after entering
the values of each group. It is also possible to perform a
calibration check without making an entry: press the
FUNC button twice when “OFF” is displayed. The instru­ment goes directly to the group check.

Before beginning calibration, be sure the internal DIP
switch V101 is open.

WARNING: Perform the calibration procedure according
to J106 jumper positions as shown in Figure 1. Other­wise, the stored calibration values may be lost.
