FAULT RELAY SETUP
LATCHING:Y
ENERGIZED:Y
SILENCABLE:Y
Use the “u” or “v” keys to move through the parameters, setting the appropriate values for each parameter as
described below. When the 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.
When the Blinking Cursor is at the end of a set of parameters for one relay, the “v” key will move the cursor to
the next relays 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 relays set of parameters.
NOTE: The parameter screen(s) will not move from the Alarm 3 Relay to the Fault Relay, or from the
Fault Relay to the Alarm 3 Relay by use of the “u” or “v” keys.
Latching
The latching parameter will determine if the relay will clear itself when a Fault or Alarm condition has passed.
If a relay is set to latching, and the relay is set to energize upon an alarm, the alarm will remain energized until
the alarm condition has passed, and the alarm is reset by use of the “RESET” switch or key. To set a relay as
latching, set the “LATCHING:” parameter to “Y”.
Energized
The energized parameter will determine if the relay is set as energized or de-energized. If a relay is set as
energized, the relay will have a normal state of being energized. When an Alarm or Fault occurs the
associated relay will de-energize. To set a relay as energized, set the “ENERGIZED:” parameter to “Y”.
Silencable
The silencable parameter will determine if a relay can be silenced if an alarm or fault condition is present. If a
relay is set as silencable, then the relay can be reset to the normal state even if the alarm or fault condition is
still present. To set a relay as silencable, set the “SILENCABLE:” parameter to “Y”.
When all of the relay 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.
4.2.7 Set Modbus™ Address
Allows the Modbus™ address of the unit to be changed. This address should not be changed unless directed
to do so by Detcon Factory Personnel.
4.2.8 Calibration Mode
“CALIBRATION MODE” disables all alarms until the calibration mode is exited.
To enter the “CALIBRATION MODE” Menu item, press the “PROG” key to enter the Main Menu. From the
Main Menu, press the “v” (Down Arrow) key until the display shows “CALIBRATION MODE”. Press the
ENTER” key to enter calibration mode.
