The power-up message is a fixed length, and only the date, time, and serial number will vary
representative of the alarm raised.
The Pump over-current disable is also a fixed-length. The “$PUMPNUM” variable is always either a “1”
or “2” depending on the pump number that has been disabled.
All other alarms have two fields that vary in length. Possible values for each of these are shown below:
The variables shown as $P1CUR, $P2CUR, and $PTHRESH are all decimal 5 digit unsigned decimal integer
numbers representative of the instantaneous value of pump current for either pump ($P1CUR $P2CUR),
or the current threshold that was exceeded ($PTHRESH). The “mA” suffix to these values is static and
will not change.
4.1.11 Sim Inserted
The SIM card insertion status is shown in the first screen. The LCD will display whether the SIM is
detected or not. This may take up to 10 seconds to update.
4.1.11.1 Network Status
The network status will show the connection status of the GSM module to the nearest cell tower.
Possible LCD messages for this are:
-Searching...
-Connected Home
-Denied Service
-Unknown status
-Roaming
Searching indicates the network module is attempting connection to a cell-tower. From starting the
BundGuard to a Connection being made, can take up to 90 seconds. This value is refreshed every second
when viewed.
Connected Home is the status in which the GSM module has successfully authenticated the SIM card
onto the network and is able to send SMS messages and transmit and receive data.
Denied service is shown when the operator refuses to authenticate the SIM card or module onto their
network. There are many reasons this may happen. A new un-authenticated SIM card is a likely culprit
for this error message.
