72 - Set Status “polarity”. - Enter 0 for normal (status is considered “ON” when grounded). Enter 1 for inverted (status is
considered “ON” when input is open or ungrounded). Example: 72, Sicon beeps, 0, Sicon beeps twice. Polarity setup
is now ended. You must enter 72 again if you change you mind.
73 – Alarm Setup. - This function lets you set the number and type of alarms for the currently active channel. Each
channel can have up to five alarms (upper & lower warning, upper & lower critical & a status alarm). Alarms may be
set for either over-value or under-value. An over-value alarm is one that exceeds a pre-programmed value that you
have specified. Conversely, an under-value alarm is one that drops below a pre-programmed value that you have
specified. Alarms may be either “warning” or “critical”. A warning alarm can cause the Sicon-8 to attempt to correct a
situation by operating a relay. Warning alarms are reported if they still exist when the user dials in, but don’t initiate
outbound calls. Critical alarms make outbound telephone calls, but do not operate relays. The Sicon-8 attempts to
rectify warning alarms up to three times, then stops. It also stops if any new alarm occurs while a warning alarm is still
pending or if a user calls in while the alarm is still pending. In that case, all current alarms go on the new alarm stack.
Setup: Enter the alarm type 1-6 as follows:
1 = Metering low warning alarm (does not call, but can activate a relay)
2 = Metering high warning alarm (does not call, but can activate a relay)
3 = Metering low critical alarm (dials out & stops any automatic action of warning alarms)
4 = Metering high critical alarm (dials out & stops any automatic action of warning alarms)
5 = Status warning alarm (does not call, but can activate a relay)
6 = Status critical alarm (dials out & stops any automatic action of warning alarms)
For metering alarms 1-4 you must now enter the alarm limit value. Asterisk (*) set a decimal and a Pound (#) must be
used to end the value. The Sicon-8 speaks the value that you entered back to you. Press 1 to confirm or 0 to re-enter.
For Status input alarms (5-6) 0 = alarm is activated when the input is grounded. 1 = alarm is activated when the input is
open. Note: The channel polarity can be reversed in software which also inverts the alarm.
For all warning alarms you must specify a relay channel, raise (*) function or lower(#) function, and the desired duration
of the contact closure in seconds. You may enter fractions of a second by using the asterisk (*). End the time setup with
the #. To de-activate relay operation enter a zero (0) instead of a relay channel number. Warning alarms are fixed in
order of occurrence.
For all critical alarms, you specify the two digit telephone dialer memory location that contains the telephone number you
wish to dial. You may specify up to five dialing sequences. Enter a # when finished.
Example #1 –
To set up a high metering warning alarm on the current channel, the sequence might go like this:
You enter DTMF 73. Sicon beeps. You enter 2. Sicon beeps. You enter a number like 10*50# which corresponds to
10.5kW. The Sicon-8 speaks the value that you entered back. Press 1 to confirm or 0 to re-enter. The Sicon-8 beeps.
Enter 01 (the channel you will activate, in this case channel 1). Enter # (the lower relay command). Enter 3*5 (for 3.5
seconds). The Sicon-8 confirms the time value by speaking “3-point-5” back to you. Confirm by entering a 1 or re-enter
the value by pushing a 0. If the meter detects a high warning alarm condition, the Sicon will now close channel one’s
relay for 3.5 seconds. It will take a reading to see if the condition still exists. If it does still exist, the Sicon will then try
twice more to correct the problem. The full programming sequence for this example is: 73,2,10*50#,1,01,3*5#,1.
Example #2 –
Set the current channel’s status input as a critical alarm:
Enter DTMF 73. Sicon beeps. You enter 6. Sicon beeps. Enter 0 (this alarm will activate if its input is grounded).
Sicon beeps. Enter 01 (this assumes you want to use the telephone number that you have stored in memory 01. You
can use 01 thru 20). Sicon beeps twice indicating that you have successfully programmed the alarm. The complete
programming sequence for this example is: 73,6,0, 01#. To add additional dialer numbers the sequence might be:
73,6,0, 01,02,03#. The alarm could also be activated when ungrounded by entering a 1 after the 6 instead of a 0.
