TVRMS2 Digital Test Kit

Chapter 1. Introduction

1–1 Description

The TVRMS2 Digital Test Kit is a light-weight, portable
test instrument designed for field testing of RMS-9, Epic,
Power+™, MicroVersaTrip Plus™, and MicroVersaTrip
PM™ Trip Units. The Test Kit includes the following
features:

• Operation from 120 Vac or six D-cell batteries.
• Trip Unit testing without de-energizing the breaker

or removing the Trip Unit from the breaker.

• Verification of switch settings on Power+, RMS-9 and

Epic Trip Units.

• Either trip or no-trip testing for time-overcurrent

characteristics.

• Monitoring of pickup current and trip time during

high-current injection testing.

• Menu-driven test procedures for ease of use.

The Test Kit interface with the Trip Unit is a three-wire
digital communication link through the test jack on the
front of the Trip Unit, as illustrated in Figure 1.

1–2 Application to Pre-RMS-9 Trip Units

The TVRMS2 Test Kit cannot be used to test earlier
MicroVersaTrip solid-state programmers. Table 1 is a
matrix showing the compatibility among types of Trip
Units and Test Kit models.

CAUTION: The older TVTS1 Test Kit cannot be used to
test RMS-9, Epic, Power+, MicroVersaTrip Plus, and
MicroVersaTrip PM Trip Units and could cause damage
to the Trip Unit if an attempt is made to do so.

ATTENTION: Ne pas utiliser TVTS1 (modèle précedent)
Test Kit avec les déclencheurs RMS-9, Epic, Power+,
MicroVersaTrip Plus, et MicroVersaTrip PM (le
déclencheur pourrait être endommagé).

CAUTION: The older TVRMS Test Kit cannot be used to
test MicroVersaTrip Plus and MicroVersaTrip PM Trip
Units and could cause incorrect test results if an attempt
is made to do so.

ATTENTION: Ne pas utiliser TVRMS (modèle précedent)
Test Kit avec les déclencheurs MicroVersaTrip Plus et
MicroVersaTrip PM (les résultants peuvent être
incorrects).
