The pulses that are counted by the PDM consist of a 'closed' state on the external contact,
followed by an 'open' state. In order to be reliably registered, the time that the contact is
'open' must be at least the Min Pulse Width, and the time that the contact is 'closed' must
also be at least the Min Pulse Width.
* When the MC-5c loses power or is disconnected from the PDM, the PDM has the capability
to record pulses using its onboard battery for power. In this situation, the sample rate of the
PDM is reduced to decrease current drain and extend battery life.
Communications Options
Although a MiniCloset-5c is typically part of an AMR (Automatic Meter Reading) System
whereby metering data is collected by a Scan Transponder using PLC, in some cases a user
may need to communicate with the meter directly. In addition to the Power Line
Communications capability that is a standard feature of the MiniCloset-5c, the following
communications options are available:
•
Local LCD (register values and certain diagnostic data are available via local LCD)
•
IEC Optical Communications Interface (optical port is standard feature; optical probe
is sold separately)
•
19.2k Internal Modem/RS232/RS485 (Option)
•
Network Data Link (4-wire RS-485) (Option)
