Configuration:
MAM number: a value from 1 to 120 is used to distinguish the 120 possible modules which can be con-
-
nected to an EAM.
3W Valve: a "no" response indicates that 2-wire latch solenoid will be used; with "yes", 3-wire latch sole-
-
noid is used.
Latch at 16V: a "no" response indicates that the voltage to activate the latch solenoid is 12 volts; with "yes"
-
the voltage is 16V.
T. sensor: indicates, in minutes, the sensor reading frequency. Setting it to 0 means no reading will take
-
place. The maximum time between readings is 200 minutes.
T. r. sen: this is the time needed to power sensor 1 so the reading will be done correctly. The unit of time
-
is 0.01 seconds. 12V of power are sent using the 12V terminal. Setting it to 0 means the sensor does not
make a reading. The maximum time is 200 x 0.01 = 2 seconds.
Delay m.: This is the minimum time needed to activate the meter pulse for it to increase the total. A pulse
-
at a lesser time will not increase the total. The time is indicated in seconds and a decimal. The default
value is 1.0".
Close R1: setting at "1" indicates that the solenoid connected to R1 will close in the event of a power cut
-
in the Monocable line.
Priority: setting to "yes" means the MAM will have a rapid response time; setting it to "no" means the MAM
-
will respond in its turn according to the number of groups per line. Only the MAM from 1 to 10 can be pri-
ority units. If MAM 1 is a priority unit, it cannot be connected to the line, and nor can 11, 21, 31... or 111.
This occurs with other numbers as well.
Manual:
In this menu option, the solenoids can be activated manually. We cannot exit this menu option if one of the
solenoids is being manually activated.
PRACTICAL TIPS:
The maximum No. of MAM's that can connect to an EAM is 120, although this number may be lower, ac-
-
cording to the section of 2-wire cable used and the total line distance.
For long distances it is better for MAM in the same group not to be connected consecutively along the li-
-
ne.
When the voltage at the end of the line is less than 20 Vdc, it is better not to name all the MAM's in one
-
group. For example, set the MAM's as 1, 4, 8, 11, 14, 18, and do not set 2, 3, 5, etc. In this way we can
make sure the voltage on the line remains uniform.
When the voltage is insufficient at the end of the line, the voltage at the EAM input can be raised to 29
-
Vdc.
The EAM and non encapsulated MAM's must be installed in a place which are protected against
-
sunlight and rain.
Encapsulated MAM's are protected against inclement weather, but if they are kept from direct sunlight, the
-
resistance of the box will be maintained over time.
