Sub-Zero VAF433-T User manual

Instruction Manual
VAF433-T / VAF433-K
Introduction
The VAF is a panel mounted 96 x 96mm Digital Panel Meter
for the measurement of important electrical parameters like
AC Voltage, AC Current, RPM, Frequency and Power Factor
VAF can be configured and Programmed On site for the
following:
PT Primary, PT Secondary, CT Primary, CT Secondary (5A
or 1A) and System Type 3 phase 3W or 4W or single-phase
system.
The front panel has Four keys using which the user can scroll
through different screens and configure the product.
Introduction
WIRING: The probe and its corresponding wires should
never be installed in a conduit next to control or power supply
lines. The electrical wiring should be done as shown in the
diagram. The power supply circuit should be connected to a
protection switch. The terminals admit wires of upto 2.5sq
mm.
WARNING: Improper wiring may cause irreparable damage
and personal injury. Kindly ensure that wiring is done by
qualified personnel only.
Maintenance: Cleaning: Clean the surface of the controller
with a soft moist cloth. Do not use abrasive detergents, petrol,
alcohol or solvents.
Notice: The information in this document is subject to change
in order to improve reliability, design or function without prior
notice and does not represent a commitment on the part of
the company. In no event will the company be liable for direct,
indirect, special, incidental or consequential damage arising
out of the use or inability to use the product or documentation,
even if advised of the possibility of such damages. No part of
this manual may be reproduced or transmitted in any form or
by any means without the prior written permission of the
company.
Controller:
Controller should be installed in a place
protected by vibration, water and corrosive gasses and where
ambient temperature does not exceed the values specified in
the technical data.
Probe: To give a correct reading, the probe must be installed
in a place protected from thermal influences, which may
affect the temperature to be controlled.
