Operation
General
After the WESROC
®
RMS Industrial LTE Cellular Tank Monitor (CTM) has been installed
on the tank to be monitored; it will periodically report tank level and activity data, and
system status information to the WESROC
®
RMS Host System (Host). Reports can be
triggered by expiration of a scheduled report interval timer, or by tank level events or
conditions.
Operating Modes
The CTM has four basic operating modes, only one of which is used during normal
operation. The other three modes are used for installation, configuration, or storage
purposes. The four modes are selected by the installer using one or two small round
programming magnets. The magnets are placed in the programming magnet recesses on
the sides of the CTM enclosure when selecting different operating modes. One
programming magnet is supplied with each CTM – it is recommended to keep a few extra
magnets on hand for use when configuring a CTM.
OFF Mode: (One programming magnet in OFF position.)
Off mode is used for storage of the CTM. This is the mode the CTM will be in when
shipped from the factory. When in Off mode, the CTM will wake up once per second and
check the position of the programming magnets. If the installer has moved the
programming magnet position(s) the CTM will switch to the newly selected mode. If not,
the CTM will resume sleeping for another second. Always leave the CTM in the Off mode
to minimize battery drain and to minimize cellular data charges when a CTM is not in use.
NORMAL Mode: (No programming magnets.)
Normal mode is used while the CTM is monitoring the level of the tank. This is the default
operating mode of the CTM once it has been installed. While in this mode, the CTM will
