For example, a command channel that controls the ON/OFF conditions of a
blower can be associated with a status channel that indicates the ON/OFF
condition of the same blower. When the status channel is accessed to
determine the blower’s status, the associated command channel can be
immediately accessed to turn the blower ON or OFF without having to enter
the access code for that command channel.
To disable a default command channel assignment for a status channel,
program the unit with the digits “0 0” when setting up this parameter. The “0
0” command-channel assignment tells the VRC2000 that no status channel
will be associated with this command channel.
• ALARM DELAY FOR STATUS CHANNEL ONE IS ... {ONE} ... [BEEP]
The delay between the time an alarm is generated and the time automatic
commands are issued can be programmed for anywhere from one to 99
seconds. Alarm delays are handy in smoothing transients and time-based
automatic functions. Once the alarm delay time passes, the VRC2000 will
issue automatic commands until the status channel’s condition changes.
Thus, an alarm is not actually issued if the condition that triggered the alarm
is cleared up before the alarm delay time has passed. Always use two digits
to enter this parameter.
• LOW INPUT IDENTIFIER FOR STATUS CHANNEL ONE IS ... {INPUT CLOSED} ...
[BEEP]
Any two words from Appendix I: Word List (See Page 125.) can be
programmed as a an identifier, such as [ON AIR] [HIGH CHARGE]
[SYSTEM OK].
• ALARM ON LOW INPUT OF STATUS CHANNEL ONE IS ... {DISABLED} ... [BEEP]
The low state of any status channel can either be enabled or disabled. The
default setting for the low state of any status channel is disabled. When
programming the VRC2000, enter “#” to enable the alarm for this parameter;
a “*” will disable the alarm for this parameter.
• COMMAND CHANNEL NUMBER FOR LOW INPUT OF STATUS CHANNEL ONE IS ...
{DISABLED} ... [BEEP]
Any command channel can be programmed to be automatically activated by a
low state on a status channel. This is called an automatic command. The
default setting, {Disabled}, indicates that there is no command channel tied
to the status channel’s low state.
To disable an automatic command-channel assignment, program the
VRC2000 with the digits “0 0” when setting up this parameter. The “0 0”
command-channel assignment tells the VRC2000 that automatic commands
should not be sent when this status-channel’s input goes low. Always use two
digits when programming this parameter.
Each command channel has two switches. If the VRC2000 is programmed
to activate a command channel when a status channel is low, the VRC2000
will ask you to select the switch to be activated for that command channel.
Enter “#” to automatically activate the B switch; enter “*” to automatically
activate the A switch.
