• CODE 10 - Digital input - Standard for I/O5, I/O6 and 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.
REMOTE SETPOINT
The remote Setpoint (SP) is enabled by an external digital signal in
either I/O5 or I/O6, when programmed with the code 8 (Select remote
SP input).
An external resistor shunt of 100 Ω is required between the terminals
7 and 8.
ALARMS FUNCTION
The controller has 4 alarms. The alarms can the configured to
operate in any of the nine functions listed on Table 3.
• Open sensor
It is activated whenever the input sensor is broken or disconnected.
• Event alarm
It activates alarm(s) in specific segments of the program. See item
7.2 in this manual.
• Event alarm
Detects a heater broken condition, by monitoring the load current
when the control output is activated. This alarm function requires an
optional device (option 3). Details of the "resistance fail" option can
be found in a specific documentation that is sent with the product
when the option is purchased.
TYPE PROMPT ACTION
Disabled off No active alarm. This output can be used as a digital
output to be set by the serial communication.
Sensor Break
(input Error)
ierr Alarm will be ON if PV sensor breaks, input signal is
out of range or Pt100 is shorted.
Event Alarm
(ramp and
Soak)
rs Can be activated at a specific segment of ramp and
soak program.

Table 3 - Alarm functions
Where SPAn means “SPA1”, “SPA2”, “SPA2” and “SPA4”.
• Minimum value
It is activated when the measured value is below the value defined in
the alarm Setpoint.
• Maximum value
It is activated when the measured value is above the value defined in
the alarm Setpoint.
• Differential (or Band)
In this function, the parameters “SPA1”, “SPA2” represent the PV
deviation as compared to the main SP.
In a positive deviation, the differential alarm will be triggered when
the measured value is out of the range defined in:
( SP – Deviation) and (SP + Deviation)
In a negative deviation, the differential alarm will be triggered when
the measured value is within the range defined above.
• Minimum differential
It is activated when the measured value is below the value defined in.
(SP - Deviation)
• Maximum differential
It is activated when the measured value is above the value defined in:
(SP + Deviation)
ALARM TIMER FUNCTIONS
Alarms 1 and 2 can be programmed to have timer functions. The 3
modes of operation are:
1- Pulse 2- delayed actuation 3- Oscillator
The desired function can be achieved programming the parameters
“A1t1”, “A1t2”, “A2t1” and “A2t2” (see Table 4).
The LEDs associated to the alarms will light when the alarm condition
is recognized, not following the actual state of the output, which may
be temporarily OFF because of the temporization.
