CENTRON Meter Technical Reference Guide 5-1
Chapter 5 Operation: C1SD, C1ST, and C1SL Versions
The CENTRON meter is available with interchangeable personality modules that
snap-into the standard CENTRON metrology base. The three multifunction
modules available include the following versions:
• C1SD—a demand module
• C1ST—a Time-of-Use (TOU) module with demand
• C1SL—a load profile module with TOU and demand
Figure 5.1 C1SL Meter with Cover
These personality modules utilize the SCS protocol which allows the C1SD, C1ST,
and C1SL meters to mimic the SchlumbergerSema 200 Register Series product line
for use with existing systems.
Features
Features of these multifunction modules include:
• Non-Volatile Memory—Programming, register, and load profile data are
stored in the EEPROM during a power outage. The TOU and load profile
modules contain a battery that maintains the clock circuitry during a power
outage.
• Optical Port Communication—Each module can be programmed to
communicate 9600 or 4800 baud through the optical tower.
• Self-Read Capability—Billing data can be stored automatically at
programmable times to be read later.
• Load Profile—The C1SL module provides 32K RAM for load profile data.
• Expansion Capability—An expansion port is available for future functions.
