68, Manifolds to t# 12345678

The X76CTM allows for the combining of two or

more tanks to generate the combined product vol-

ume of physically manifolded tanks. If tank 2 is

manifolded to tank 1, the reports for tank 1 will

contain the manifolded volumes, while those for

tank 2 will not.The same applies to the leak test.

The leak test for tank 1 will use the combined

product volume, while tank 2 will be independent.

Manifolding tanks is performed with Function 68.

The display has 8 characters for every tank where

the current tank is marked with a black block.

Manifolds to t# 12345678

1-8 to set/clr: ...* ...

Press the key, corresponding to the tank number to

be manifolded, to toggle the status of the tank (i.e.,

if tank is not manifolded, it will manifold and vice

versa). Pressing the digit that corresponds to the

current tank does not cause a change.To end

manifolding, press [DISPLAY].

76, High-Water Level Alarm

The high water alarm is set using Function 76.

High water level alarm

3.5 in

The high water alarm warns when the water level

has exceeded a preset level.When this set point is

exceeded, an audible/visual alarm is generated fol-

lowed by a printout of the alarm. The high water

alarm can be programmed to an external output

relay (Function 81). Information on the last water

alarm warning for each tank is stored in memory.

79,Theft Detect Threshold

Use Function 79 to set up the theft detect thresh-

old. A message will be displayed:

Theft detect threshold

10.0 gl

Enter the number of gallons loss that will make the

theft gallon alarm active and press [ENT.].

NOTE: This function is only active when in THEFT

DETECT MODE (Function 292).

82, Set Up Tank Alarm

The X76CTM can be configured to perform differ-

ent actions when an alarm occurs. For each event,

a relay can be assigned.The events supported

are:

be conducted.The higher it is, the easier it is to

enter a leak test, but the data could be noisier and

the results incorrect

Leak scatter

0.2 gl

The activity threshold is used to distinguish tank

leakage from real activity - delivery of sale. It can

be increased to the minimal throughput of the dis-

penser pump. By default this is 9 gl/h.

Activity threshold

9.0 gl

Temperature scatter controls what temperature

slope is acceptable to start a test.

Temp scatter

0.2 deg/h

Minimum test duration sets the minimum accept-

able test time to be used by the CSLD database.

Min test duration

15 min

A maximum test duration of 120 minutes is suffi-

cient for tanks up to 20,000 gallons. Increasing this

duration usually will not improve the result and

degrade the response time.

Max test duration

120 min

Precise wait after delivery can be entered to in-

crease the test precision, although it is not needed

in most cases.

Precise wait after delivery

360 min

This parameter allows the X76CTM to use a lower

threshold for the Precise Test. Generally, this

increases the probability of false alarms, but allows

for early warning of possible tank leak.

0.1 gph test? No

The minimum CSLD duration sets a minimum com-

bined test time for the CSLD algorithm to make its

conclusions. Generally, the longer it is, the better.

Min CSLD duration

8 hours

The minimum history parameter sets the maximum

number of days to be used by CSLD to acquire the

minimal test duration. If there is not enough tests

for this period, increasing the number of days is

recommended. If it is not possible to acquire the

data for one month, the tank should be shutdown

and a normal test conducted.

Min CSLD history
