• DEFAULT COMMAND CHANNEL FOR METERING CHANNEL ONE IS ... {DISABLED} ...
[BEEP]
Any command channel can be tied to any metering channel. This allows
commands to be issued directly, immediately after requesting metering-
channel information.
When the VRC2000 has been accessed with the user access code, enter “*”
to activate the A switch of the default command channel when you are
reading metering channel 1. Enter “#” to activate the B switch of the default
command channel when reading metering channel l.
When programming this parameter, enter “0 0” to disable the default
command channel for the selected metering channel. Always use two digits
to program this parameter.
• ALARM DELAY FOR METERING CHANNEL ONE IS .... {ONE} ... [BEEP]
The time delay before alarms are generated and automatic commands are
issued is user-programmable (from one second to 99 seconds). Alarm delays
are handy in smoothing transients and time-based automatic functions. Once
the alarm delay time passes, the unit will issue automatic commands until
the metering channel’s input condition returns to a nominal (non-alarm)
level. Always use two digits to program this parameter.
• PHONE NUMBER FOR METERING ALARM ONE IS ... {DIAL ALL} ... [BEEP]
The VRC2000 can be programmed to dial any single outbound telephone
number or all of the outbound telephone numbers entered into the unit’s
memory when an alarm on a metering channel is sensed. The default setting
is {Dial All}, which indicates that the VRC2000 will dial, in sequence, all
numbers presently entered into the unit’s outbound telephone number
memory.
To set up the VRC2000 to dial all of the telephone numbers in sequence,
program this parameter with a “0”. To program this parameter to dial a
single outbound telephone number, enter the single-digit number which
corresponds to the number you want the VRC2000 to dial. For example, to
program the VRC2000 to dial outbound telephone number 1 when an alarm
is generated by this metering channel, enter “1”.
• SECOND LOW LIMIT OF METERING CHANNEL ONE IS ... {MINUS, NINE THOUSAND,
NINE HUNDRED, NINETY-NINE} ... [BEEP]
When setting tolerance limits for each metering channel, set them according
the result of the calibration constant multiplied by the voltage or current
sample.
• COMMAND CHANNEL NUMBER FOR SECOND LOW LIMIT OF METERING CHANNEL
ONE IS ... {DISABLED} ... [BEEP]
This parameter allows a specific command channel to be selected in order to
automatically activate if the second low tolerance limit on a metering
channel is passed (i.e. an automatic command). Also select the switch to be
fired for that command channel. Enter “#” to automatically activate the B
