Leak Setup
The Leak Setup menu has the following submenus:
▪
ReAlarm Int (Re-Alarm Interval)
▪
Auto Reset
▪
AudibleAlarm
▪ Alarm Reflash
▪
Alarm Reset
These parameters determine the alarm setting for all SIMs. Password entry is required to
change them.
RE-ALARM INTERVAL
The TTDM can be set to re-alarm automatically if the alarmed event has not been cleared
after a certain length of time.
−
allowed range: 0 – 24 hours (default = 0)
H
INT
: Use this to automatically alert the next shift when the system has an uncleared event
(leak, cable break/fault, or service required).
AUTO RESET
The TTDM is factory set to require a manual reset following a leak event. This allows the
user to verify that any equipment connected to the Leak relay is ready to be switched back
to its normal state. Note that this setting is independent from the TTSIM-1A/TTSIM-2 relay
reset mode.
If Auto Reset is set to “On,” the leak relay will automatically reset as soon as the leak has
been cleared.
−
choices: Off / On (default: Off)
AUDIBLE ALARM
The audible alarm may be disabled if not required. See feature 27 on page 16 to adjust
the volume.
−
choices: Off / On (default: On)
ALARM REFLASH
The alarm reflash option causes the leak alarm relay contacts to revert to their no-alarm
state for approximately 5 seconds then return to the alarm state whenever an additional
leak occurs before an existing leak is cleared. This is useful when a multi-channel system
is connected to a host computer via a simple relay-only interface. Refl
ash will typically
cause the host computer to log each new leak event as it occurs whether or not preceding
events have been cleared.
−
choices: Off / On (default: Off)
ALARM RESET
This parameter determines whether all SIM channels will be reset simultaneously when
the Reset key is pressed (All setting), or only the currently displayed SIM channel will be
reset (Single setting).
−
choices: Single / All (default: Single)
