MANAGING DIGITAL INPUTS
CODITEL 2 has two digital inputs whose status is signalled by a green LED
(on
 input short circuited, off  input open).
The following can be connected to these inputs:
− signals from a relay
− signals from an open collector
− signals with voltage (maximum 40Vdc)
− signals from pulse meters or time meters
Note. The maximum measurable pulse length is 20ms (max frequency 25Hz).
Some alarms can be defined on these inputs:
− on the input status
− on the count of the pulse meter
− on the value of the time meter
The following commands allow the digital signals to be managed:
• Setting the operating mode
To set the operating mode of a digital input so that it detects an alarm in a special
condition, use the command:
DIG
[input number][func mode][parameters][alarm time setting][unit]
− [input number]  number of input 1 or 2
− [func mode]  OPEN, CLOSE for alarm on the open or closed status of the
input respectively, TIMER to set the input as time meter,
PULSE to set the input as pulse meter
− [parameters]  OPEN, CLOSE indicates the alarm delay time (max 2
32
-1 s),
TIMER the open or close active count status,
PULSE the count front OPENCLOSE or CLOSEOPEN
− [unit]  time unit s seconds, m minutes, h hours (parameter for OPEN,
CLOSE func modes only)
Some examples:
DIG 1 OPEN 10 S
 alarm if input 1 remains open for at least 10 seconds
DIG 1 CLOSE 20 M  alarm if input 1 remains closed for at least 20 minutes
DIG 1 TIMER OPEN  counts the time when input 1 remains open
DIG 2 TIMER CLOSE  counts the time when input 2 remains closed
DIG 2 PULSE OPENCLOSE  counts the pulses on open  closed variation of input 2
