*These parameters can be viewed but not changed if the cycle is
protected.

**Requires a key combination to access the cycle.

Press

to advance and

to go back in the menu cycle.

Keep pressing the

key to move fast forward or backward.

Press

and

simultaneously to move from one cycle to the next

one.

At the end of each cycle the controller returns to the operation cycle.

PROGRAM SECURITY

Each menu cycle can be locked (protected) by pressing

and

simultaneously for 3 seconds. Press

and

for 3 seconds to

unlock. A short blink of the display confirms the lock/unlock change.
This will alternately lock or unlock the

and

keys to avoid

tampering.

For further protection, the unlock operation through the keypad may
be disabled by changing the position of an internal strap inside the
controller:

When PROT is OFF, the user is allowed to lock and unlock the
cycles using the keypad as explained above. If PROT is ON, the
cycles lock/unlock operation is disable.

OUTPUTS, ALARMS AND DIGITAL INPUTS CONFIGURATION

The controller input/output channels can assume multiple functions,
depending on configuration: control output, alarm output, digital
output, digital input, and PV or SV analog retransmission. These
channels are identified as I/O1, I/O2, I/O3, I/O4, I/O 5 and I/O6.

The basic controller model comes loaded with:

•

I/O1 and I/O2 - SPDT relay output;

•

I/O3 and I/O4 – SPST relay output;

•

I/O5 - analog output (0-20 or 4-20 mA), pulse 10 V max, digital I/O;

•

I/O6 – Digital Input;

The function code of each I/O can be selected among the options on
Table 2. Only valid function codes are displayed for each I/O (for
example, I/O1, which is a relay, can be configured with functions 0 to
5 only; on the other hand, I/05 can perform all 16 functions).

The description for the functions follows:

•

CODE 0 - No function. The I/O channel programmed with code 0
will not be used by the controller. It is available to be used by serial
communication as digital output.

•

CODES 1 to 4 - Alarm output - Available for all I/O channels
(except I/O6). The selected channel can be used as output to
Alarms 1 to 4.

•

CODE 5 - PWM control output - Available for all I/O channels
(except I/O6).

•

CODE 6 - Digital input - Standard for I/O5 and I/O6.

Closed: Manual control
Opened: Automatic control

•

CODE 7 - Digital input - Standard for I/O5, I/O6 and

key.

Start/Stop input (“rvn

rvn

rvn”: YES / no).

Closed: outputs enabled
Opened: outputs disabled

•

CODE 8 - Digital input - Standard for I/O5, I/O6 and

key.

Closed: remote SP (4-20 mA in remote SP input)
Opened: main SP (internal programmed SV)

•

CODE 9 - Digital input - Standard for I/O5, I/O6 and

key.

Opened: enables R&S program

Closed: holds R&S program (the program resumes when the contact
is opened again)

key.

Selects R&S program 1. Used to alternate between the main
Setpoint and a second Setpoint defined by the R&S program 1.

Closed : selects program 1
Opened: uses main Setpoint

•

CODE 11 - Analog control output - I/O5 only. 0-20 mA control
output.

•

CODE 12 - Analog control output - I/O5 only. 4-20 mA control
output.

CODES 13 to 16 - Analog retransmission. I/O5 only. Configures I/O5 to
output a 0-20 mA or 4-20 mA analog signal proportional to PV or SP.
