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.

This parameter is shown before protected

cycles. See item Configuration Protection.

Calibration

Entry of value close to the beginning of scale

in 4-20 mA input, within scale specified in
InLL

and InKL.

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.
