i

ii

The secondary of an external current transformer must never be allowed to be open circuit when the primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage, fire and even serious or fatal injury. Ensure that the current transformer wiring is made through shorting switches and is secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.

Setup procedures must be performed only by qualified personnel familiar with the instrument and its associated electrical equipment.

DO NOT open the instrument under any circumstances.

screen with a programmable scroll interval of 2 to 15 seconds. Automatic return to the main screen is available after 30 seconds of uninterrupted use. The front panel also includes:

bar graph showing percentage load with respect to user-definable nominal

(100%) load current

alarm LED providing a local indication when a predefined alarm condition appears. The alarm LED is shut off manually (by pressing on both up and

down keys more than 5 sec)

RXD/TXD LEDs showing communications receive/transmit status

Setup is menu driven, with optional password protection. 16 programmable setups are provided for alarm and control functions (for programmable parameters, see ‘Measured Parameters’ below).

Communications are available using an RS-232 or RS-485 standard (factory set), with ASCII/Modbus (and optional DNP3.0) protocols. 120 user assignable registers are available in ASCII/Modbus protocols.

Eight relays are provided for energy pulsing (KYZ) or alarm and remote control.

ENTER

Your instrument provides 16 alarm/event setpoints that can monitor a wide variety of events; in turn, these events can be programmed to trigger specific actions. This menu is used to specify the events to be monitored by the setpoints, and actions to be triggered by those events.

To program a setpoint, you might need to define up to six setup parameters which include: the setpoint trigger parameter, operate and release limits, optional operate and release delays, and the setpoint action. Table 4-6 explains the setpoint setup parameters. For the entire list of available triggers and setpoint actions, refer to Tables 4-7 and 4-8.

When a setpoint is operated, its status is always stored to the alarm status register even if no action is assigned to the setpoint. The alarm status register can be polled and cleared through communications.

This action causes the alarm LED on the front panel to blink that gives the user a local alarm indication. The alarm LED operates in latched mode, i.e., even if an alarm condition disappears, the alarm LED is still blinking until the user acknowledges the alarm from the front panel (see Section 5.1). An alarm LED can be operated from any number of setpoints using an OR scheme.

Alarm relays operate in unlatched mode. This means that a relay is operated while an alarm condition is present and is automatically released when an alarm condition disappears. Each relay can be operated from any number of setpoints using an OR scheme, i.e., a relay will be in operate state while either of the alarm conditions is still present.

This action converts a common event counter to the time counter which measures time at 0.1 hour resolution while the setpoint is in the operated state. Each time counter has a non-volatile shadow counter that counts time at 1-second resolution before the corresponding time counter is incremented. The time counters can be inspected via the

Status Information Menu. They are labeled by an hour mark in the middle window.

This menu allows you to set the relay operation mode: non-failsafe or failsafe.

Failsafe relay operation is the opposite of normal operation where relay contacts are closed when a relay is operated (activated), and are open when a relay is released (de-activated). In failsafe mode, an alarm is activated by a nonenergized relay which will open in all cases when an alarm condition is present or an alarm setpoint is not operational either due to a loss of control power or due to corruption of the setpoint setup configuration. A failsafe relay is closed only if it is under setpoint control and no alarm conditions exist, or if it is manually operated via communications.

When pressed for 5 seconds, clears the alarm LED arrow LEDs - indicate measured parameter

Load bar graph indicates % current load round LEDs indicate measurement group

The front panel display is updated approximately twice per second; you can adjust the display update rate via the Display Setup Menu (see Section 4.8).

Table 5-1 lists all displayed parameters and their LED indicators.

Chapter 5 Data Display 39

Load Bar Graph

The load bar graph displays the amount, in percent, of the current load with respect to user-defined nominal load current. The highest current measured by the C191HM is divided by the nominal load current as defined in the Display

Setup Menu (see Section 4.8) and expressed as a percent by the LEDs (40% to

110%) which are lit. For example, if all LEDs up to and including 90% are lit, this means that the load is 90% of the nominal load current. If the nominal load current is set to 0, it is taken from the CT primary current setup.

Alarm LED

The blinking Alarm LED gives you an alarm indication. It is controlled by the alarm/event setpoints (see Section 4.6) and operates in latched mode. Even if alarm conditions are no longer present, the alarm LED will continue to blink. To clear the alarm LED, press the up/down arrow keys simultaneously for 5 seconds.

Auto Scroll

If display Auto Scroll option is enabled (see Section 4.8), the common measurements display (main screen) will scroll automatically after 30 seconds of uninterrupted use.

To stop auto scrolling at the current page, press either arrow key.

Auto Return to the Main Screen

If display Auto Return option is enabled (see Section 4.8), the display will automatically return to the main screen from any other measurement screen after

30 seconds of uninterrupted use.

Fast Reset of Accumulated Data

When changing data via the front panel is not secured by a password, you can reset the Min/Max registers, maximum demands and energies from the display mode without entering the reset menu.

Display readings for all electrical quantities except Min/Max log and energies are sliding average values.

When using direct wiring (PT Ratio = 1), voltages are displayed in 0.1 V units, currents in 0.01 A units, and powers in 0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio >

1), voltages are displayed in 1V units, currents in 0.01 A units, and powers in 0.001

MW/Mvar/MVA units. When the value width is over the window resolution, the right most digits are truncated

By default, the maximum range for energy readings is 99,999,999 MWh/Mvarh/MVAh.

Beyond this value, the reading will roll over to zero. When the energy reading exceeds the window resolution, the right-most digits are truncated. To avoid truncation, you can change the energy roll value to lower limit via the User Selectable Options menu (see

Section 4.9). Negative (exported) energy readings are displayed without a sign.

Per phase power and power factor readings are displayed only in 4LN3/4LL3 and

3LN3/3LL3 wiring modes (see Section 4.1) if the phase powers display is enabled in the Display Setup menu (see Section 4.8).

Chapter 5 Data Display 45

Phase energy readings are displayed only in 4LN3/4LL3 and 3LN3/3LL3 wiring modes if they are enabled in the User Selectable Options menu (see Section 4.9).

When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be line-to-line voltages.

5.3 Self-Test Diagnostics Display

The C191HM periodically performs self-test diagnostics during operation. If the instrument fails the test, it discards the last measurement results, and an error code is displayed for one second on all LEDs. Error codes are listed in Table 5-2.

Code ‘8’ indicates normal operation.

Frequent failures may be the result of excessive electrical noise in the region of the instrument. If the instrument continuously resets itself, contact your local distributor.

NOTE

The C191HM provides a self-check alarm register accessible through communications that indicates possible problems with instrument hardware or setup configuration. The hardware problems are indicated by the appropriate bits which are set whenever the instrument fails self-test diagnostics or in the event of loss of power. The setup configuration problems are indicated by the dedicated bit which is set when either configuration register is corrupted. In this event, your instrument will use the default configuration. For more information on the self-check alarm register, refer to the communications reference guides shipped with your instrument.
