FREQUENTLY ASKED QUESTIONS
AUTOMEG/SUBMEG
Q. Can the AUTOMEG/SUBMEG be by-passed in the event of an emergency?
A. Yes. An emergency by-pass switch is incorporated into the design of the AUTOMEG/SUBMEG.
|
Q. Can the AUTOMEG/SUBMEG be used with variable frequency drives (VFD) or solid state motor starters?
A. Yes. However a contactor must be used to isolate the motor windings from the solid state circuitry during the test cycle.
|
Q. Does the AUTOMEG/SUBMEG monitor the motor winding insulation while the motor is running?
A. No. The AUTOMEG/SUBMEG monitors the motor winding insulation only when the motor is NOT running. (Please see last question).
|
Q. Does the AUTOMEG/SUBMEG monitor the motor winding insulation continuously when the motor is NOT running?
A. No. The AUTOMEG/SUBMEG tests the insulation for only 10 seconds prior to starting.
|
Q. Does the AUTOMEG/SUBMEG inhibit the motor from starting when the low meg alarm is activated?
A. Yes. If that option is chosen.
|
Q. Can the circuitry of the insulation monitor be tested to insure reliability?
A. Yes. A confidence test is provided by a manual test button which allows the user to test the internal circuitry of the insulation monitor.
|
Q. Is the AUTOMEG/SUBMEG adaptable to telemetering?
A. Yes. A set of contacts are provided for external use.
|
Q. Is the AUTOMEG/SUBMEG available in various insulation trip values?
A. Yes. The AUTOMEG/SUBMEG is available in various trip values from one (1) megohm to ten (10) megohm.
|
Q. Does the AUTOMEG/SUBMEG indicate when the motor insulation is being tested?
A. Yes. A sunlight visible LED indicates when 500 volts DC is applied to the motor insulation.
|
Q. What type of equipment can the AUTOMEG/SUBMEG be used with?
A. The AUTOMEG/SUBMEG can be used to test all AC and DC motors and generators.
|
Q. Can the AUTOMEG/SUBMEG be retrofitted into existing control panels?
A. Yes. The AUTOMEG/SUBMEG can be retrofitted into existing control panels in less than one hour.
|
Q. Can the AUTOMEG/SUBMEG be operated on other than 120 volts AC?
A. Yes. The AUTOMEG/SUBMEG can be operated on 240VAC or 24VDC.
|
Q. Can the AUTOMEG/SUBMEG be used to monitor the idle motor continuously?
A. Yes. In certain circumstances the AUTOMEG/SUBMEG can be used to monitor the idle motor continuously.
