CALIBRATION CYCLE
All input and output types are factory calibrated. If recalibration is
required, it must be performed by a specialist. If this cycle is
accidentally accessed, go through all parameters without changing
values.
PASS
Password
Access Password entry.
This parameter is shown before protected
cycles. See item Configuration Protection.

Calibration
Enables calibration.
inL(
Input Low
Calibration
Entry of value close to the beginning of scale
in 4-20 mA input, within scale specified in
InLL
and InKL.
inx(
Input High
Calibration
Entry of value close to the end of scale in 4-20
mA input, within scale specified in InLL and
InKL
.
ovL(
Output Low
Calibration
On this screen, whenever you press or
, a standard current close to 4 mA will
be applied. Measure current, in mA, and enter
it on this screen.

Calibration
On this screen, whenever you press or
, a standard current close to 20 mA will
be applied. Measure current, in mA, and enter
it on this screen.

CONFIGURATION PROTECTION
The indicator allows configuration protection as determined by user,
preventing unauthorized changes. The Protection (PROt) parameter,
in the Calibration cycle, determines the protection level to be
adopted, limiting Access to cycles, as shown in the table below.

Table 14 – Configuration Protection Levels
Access Password
To access the protected cycles, it is necessary to enter an Access
Password that allows altering the configuration of parameters in
these cycles.
The access password is entered in the Pass parameter, which is
shown in the first of protected cycles.
Without a protection password, parameters of the protected cycles
can be only viewed.
The Access Password is defined by user in the Password Change
(PA.(k) parameter, shown in the Calibration cycle.
New indicators come from factory with access password “1111”.
MASTER PASSWORD
If you forget the access password, it is possible to use the Master
Password feature. When this password is entered, users gain access
to the Password Change (PA.(k) parameter and are allowed to
specify a new access password to the indicator.
The Master Password consists of the last three digits of the indicator
serial number added to the number 9000.
For example, for a device with serial number “12154321”, master
password is “9 3 2 1”.
MAINTENANCE
PROBLEMS WITH INDICATOR
Connection errors and inadequate programming are the main
problems when using the indicator. A final review should prevent
losses and wasting time.
