test Mode Test Mode: Choose between four different In-Tank Leak Test Modes to best suit the combined
needs of the operator and tank requirements.
Entry Type: select list
Range Limits: MAnuAL (Manual): an on-demand test manually started each time by authorized
site personnel.
time (Timed/Scheduled): a scheduled test including monthly, weekly and even
daily test options. The scheduling is defined in the Leak Test menu.
Auto (Auto): generally used to support a twenty-four hour facility where the
usage is unpredictable making a scheduled test difficult to complete within the
month. The TMS monitors site pump or generator activity using a CC Input
(enabled as Relay) that is typically wired to a CS-10 current sensor. The TMS
determines the optimum time to start a test and will continue to attempt to
complete a test until the monthly testing requirements have been satisfied.
rELAy (Timed Relay): a scheduled test typically used to support a manifolded
tank set. The TMS can isolate a tank by changing the state of up to three relay
outputs at the scheduled start time of the test. The actual test begins fifteen
minutes later to allow the tank contents to stabilize.
Default/Initialized value: ManuaL
LEAkLimit Leak Limit: The Leak Limit is used to select the leak threshold of the test performed. Most States
typically require either a 0.2 GPH [0.8 LPH] or 0.1 GPH [0.4 LPH] for a regulated UST. Check
with the local regulators to determine what the local leak threshold requirements are prior to
configuring the In-Tank Leak Test.
Entry Type: 1-digit numeric
Range Limits: 0.0 - 0.9 GPH [0.0, 0.4, 0.8 LPH]
Default/Initialized value: 0.0
threshoLd Threshold: Represents the minimum percent volume required to perform an In-Tank Leak Test.
The TMS is capable of performing an In-Tank Leak Test on tanks up to 20,000 Gallons with as
little as 20% of the tank capacity filled with liquid. Tanks up to 75,000 Gallons currently require
50% of the tank be filled with liquid. Refer to the National Workgroup website, www.nwglde.org,
or contact Pneumercator for up to date information on testing requirements.
Entry Type: 2-digit numeric
Range Limits: 20-99
Default/Initialized value: 20
Auto mode Auto Mode Pass/Fail Select: Defines the required test result that qualifies to satisfy the monthly
requirements. Once the requirements have been satisfied, no further tests are performed for
the duration of the month. This context-sensitive menu is only visible when the Test Mode is set
to AUTO.
Entry Type: select list
Range Limits: Pass: The first test with a Passing result satisfies the monthly requirement
P-F: Any completed test, Pass or Fail, satisfies the monthly requirement
Default/Initialized value: Pass
Pump-gen Pump/Generator: The CC Input number that represents the pump or generator activity. The
activity is monitored by the TMS in support of an Auto Leak Test. The TMS determines the best
opportunity to begin the leak test based on this information. This is typically provided by the
CS-10 current sensor but may be provided from a third-party source. This context-sensitive
menu is only visible when the Test Mode is set to AUTO.
Entry Type: 1 digit numeric
Range Limits: CC NO: No CC Input selected
CC 1-16 (TMS3000), CC 1-10 (TMS2000)
Default/Initialized value: no
