1.5.2
Binary Outputs – Timer
There are 6 internal outputs and 10 optional external outputs for the unit. The contacts can
switch up to 300 VAC, 1 Amp or 250 VDC, 1 Amp continuous. The contacts may be to open or
closed, thus simulating circuit breaker operation. The programmable wait duration is from 1
millisecond to 10,000 milliseconds.
1.6
Battery Simulator
The receptacles provide 24, 48, 125, or 250 VDC with current limiting protection. The primary
application is to provide DC logic voltage to solid-state and microprocessor relays.
CAUTION:
NOTE: DC voltage is ON and available when the output is turned on using
the LCD touch panel or via software command. Do not plug or insert any
test lead into the BATTERY SIMULATOR binding posts without first
connecting the test leads to the load!
1.7
Transducer DC IN Measuring Circuit
The DC measuring circuit’s voltage is from 0
±
10VDC and current from either 0
±
1mADC or 1 to
±
20mADC. This circuit is used for testing transducers. See Section 3.8.10.4 for more description.
1.8
Operation of Optional High Current Interface
The High Current Interface may be initiated in the Main Menu Screen. The High Current Interface
button is located at the bottom of the TVI. When initiated, the “High I” will change to “Unit I”.
When a relay test is completed and the
HIGH CURRENT INTERFACE is no longer required, turn
OFF the EPOCH-20/II test unit.

SETUP
2.1
System
Unpack the unit and check for evidence of any shipping damage. If there is any visual damage,
notify the freight carrier to make a damage claim and notify Megger of the damage.
CAUTION
Potentially lethal voltages may be present on the output terminals. It is
highly recommended the operator read the user manual thoroughly and have an
understanding of the test set operation prior to turning power on.
1. Plug the Touch View Interface into the front of the unit. The TVI will be active once the
power is turned ON. A personal computer (PC) will take control of the unit if it is
connected. The unit power must be OFF before the PC is connected to the unit.
