page content text Smart Series ® Digital Current/Voltage Monitor Smart Series ®
Streamlined Design For Improved Performance The new Current/Voltage Monitor is simple to operate and features a large easy-to-read digital display. Ease of operation has been enhanced by streamlining the unit and eliminating unnecessary switches and controls. When setting the selector switch to the desired zone number, the ‘AMPS’ function is selected. The meter will then display the amount of current being delivered by the selected module. Input voltage to the system can be measured by rotating the selector switch to one of the three ‘line voltage’ positions. This will set the meter in the ‘voltage’ function and display the voltage of the selected phase. Current Supply To Each Zone To monitor the current supply to each zone, simply set the rotary selector switch to the desired module zone number. The “AMPS” function is then automatically selected and is indicated by the letter ’A’ just to the right of the numbers in the display window. The meter displays the current being delivered to the heater load in amperes. Input Voltage From Each Phase Set the rotary selector to the desired phase voltage position. This automatically selects the ‘volts’ function which is indicated when the letter ‘V’ appears to the right of the numbers in the display window. The meter will display the line voltage of the selected phase. 1. CIRCUIT BREAKER/DISCONNECT – Applies or removes power to all modules in the frame. 2. POWER ON LIGHT (amber) – Illuminates when CIRCUIT BREAKER is in the ON position. 3. AMPS/VOLTS METER – Digital multi-scale meter provides accurate readings of zone current (AMPS) or input voltage (VOLTS). 4. AMPS/VOLTS INDICATOR – Appears automatically when either AMPS or VOLTS is selected.

5. SELECTOR SWITCH – Multi-position switch automatically selects zone current or phase line voltage to be monitored. For systems with more than 12-zones, additional meter and selector switch panels are supplied. Specifications Voltmeter Range 190 to 290 VAC (for 240 volt systems) 90 to 145 VAC (for 120 volt systems)
NOTE: The Digital Current/Voltage Monitor is a factory installed option which replaces the standard circuit breaker/disconnect, and is supplied when “CV-style” mainframes are ordered.
