Leak Detection and Location Events
A LEAK ALARM
When liquid is detected by sensing cable in any channel, the following occur:
▪
The audible alarm sounds.
▪
The red Leak LED illuminates.
▪
The display changes to show the channel and location of the leak.
▪
The interfaces signal the event (Leak relay, 4-20 mA, and serial port)
CH01 USER_LABEL_0001
Leak 1662 ft
HH:MM DD-MON-YYYY
The following actions should be taken:
►
Silence the alarm (if necessary).
►
Locate the leak.
►
Clear the system.
►
Reset the leak relay. (This occurs automatically if Auto-Reset is enabled; see page 30.)
H
INT
: If audible alarms are not required, the module can be set to disable them (see page
30).
TO LOCATE THE LEAK
Using the channel number and location displayed by the TTDM-PLUS, refer to the system
map and determine where the leak was detected.
TO CLEAR THE SYSTEM
Fix the leak and clean up the area affected. Then dry the sensing cable (in the case of
TT1000 and TT3000) or replace the tripped section (TT5000 series). Once the sensing
cable is clear, the module responds and the display changes:
CH01 USER_LABEL_0001
Leak Cleared
Press reset
HH:MM DD-MON-YYYY
Notice that the red LED remains on. This indicates that the leak relay is still in the alarm
state.
TO RESET THE LEAK RELAY
In order to reset the leak relay and return the module to the “SIM Normal” state, press the
Reset button. Before doing so, check that any external equipment controlled by the leak
relay is ready to be reset.
Once the R
ESET
button is pressed, the relay returns to normal, the red Leak LED
extinguishes, and the LCD returns to the normal display.
H
INT
: If manual reset is not required, the TTDM-128 can be set to auto-reset; see page 30.
