Blinking Cursor is positioned over the colon (“:”) of the parameter to be changed, use the “ENTER” key to
make changes to the parameter. The parameter will be displayed in brackets “[ ]” to signify the ability to
change that parameter. Once the correct parameter has been set, use the “ENTER” key to accept the change.
The Cursor will change back to a Blinking Cursor, and the arrow keys can again be used to move through the
parameters.
NOTE: Each channels Range and Decimal point values, in the “SET CHANNEL DATA” menu, must be
set properly before that channels alarm parameters can be set.
When the Blinking Cursor is at the end of a set of parameters for one channel, the “v” key will move the
cursor to the next channel’s set of parameters. Likewise, when the Blinking Cursor is at the beginning of a set
of parameters for a channel, the “u” key will move the cursor to the previous channel’s set of parameters.
NOTE: The parameter screen(s) will not move from the last channel to the first channel, or from the first
channel to the last channel by use of the “u” or “v” keys. The last channel available is determined by the
number of channels set active via the “SET # OF CHANNELS” menu.
ALM LEVEL:
Alarms 1, 2 and 3 are all set in the same manner. This parameter is used to set the alarm point for each alarm.
The alarm level is adjustable from 1 to the maximum range set in the “RANGE” parameter of the “SET
CHANNEL DATA” menu for the sensor selected. (I.E. if the sensor range is 1000, the maximum set point for
the alarm would be 1000.) Use the “u” or “v” keys to set the appropriate value for the alarm set point. Use
the “ENTER” key to accept the value. Set the alarm level set points for alarms 1, 2 and 3.
NOTE: Each channels Range and Decimal point values, in the “SET CHANNEL DATA” menu, must be
set properly before that channels alarm parameters can be set properly.
ALM1 ASCENDING:
This parameter is used to set the alarms as ascending or descending. Alarms 1, 2 and 3 are all set in the same
manner. Use the “u” or “v” keys to change the value from “Y” (yes) to “N” (no). Set to “Y”, the alarm will
be set as ascending, set to “N”, the alarm will bet set to descending. Use the “ENTER” key to accept the
value. Set the Alarm Ascending parameter appropriately for alarms 1, 2, and 3.
When the Blinking Cursor is at the end of a set of parameters for one channel, use the “v” (Down Arrow) key
to move the Blinking Cursor to the next channel’s set of parameters. Continue on to set all of the parameters
for each sensor.
NOTE: Each device’s alarm parameters must be set correctly for the unit to function properly.
When all of the channels parameters have been set properly, press the “PROG” key to exit the menu and use
the “u” or “v” keys to move to the next or previous menu item, use the “PROG” key to exit the Main Menu, or
allow the unit to time out and the unit will return to Normal Operation after about 15 seconds.
4.2.6 Set Relay Function
“SET RELAY FUNCTION” allows the relays to be set as Latching/Non-Latching, Energized/De-Energized,
and Silanceable/Non-Silenceable. The menu item will go through all 4 relay settings starting with the Fault
Relay, and continuing on through Alarm 1, Alarm 2, and Alarm 3 Relays.
From the Main Menu use the “u” or “v” keys to move to the “SET RELAY FUNCTION” menu item and
press the “ENTER” key to enter the “SET RELAY FUNCTION” menu. The LCD will display the current
parameters for the Fault Relay:
