Veeder-Root V454502 User manual

Introduction
A new standard of performance and functionality in a compact preset
counter. The V454502 Dual Preset Counter offers a pre-settable
counter with full calibration for a variety of applications.
The bright red LED display provides simultaneous count and preset
indication. The use of annunciators and simple key sequences makes
operator changes quick and easy. A variety of count sources are
accommodated, including relay and pushbutton contacts, photocells
and proximity switches and uni- or bi-directional incremental encoders.
The open collector output can interface to light duty devices and the
relay contacts offer heavy duty load switching.
Set-up and installation are simplified
through
front panel entry of configuration
parameters
and a unique “no tools required” panel
mounting bracket.
The V454500 family of preset counters
combines state-of-the-art circuitry and
electronic assembly techniques with an
ergonomic package design that results
in the most cost-effective ,
high-performance counter value
on the market.

I N S T A L L A T I O N
AC Power Input
Connect AC power to Terminal 7 (Line) via a 1A
slow-blow fuse and to Terminal 8 (Neutral) - see below.
AC power should be from a separate branch circuit
which is noise-free and does not feed heavy loads.
DC/Low Voltage AC Power Input
Connect DC/low voltage AC power to Terminal 7 (+)
via a 0.5A slow-blow fuse and to Terminal 8 (–) - see
below. DC power should have low ripple and be
noise-free.
Current Sourcing (PNP) Count Inputs
Connect Add count input to Terminal 2 (A) and/or Subtract
count input to Terminal 3 (B) - see below. In Configuration
Mode, set PuLLparameter to no and, for Add/Subtract
operation, set InPuparameter to A-B .
PNP Open Collector
Contact Closure
Current Source or
Line Driver
Current Sinking (NPN) Count Inputs
Connect Add count input to Terminal 2 (A) and/or Subtract
count input to Terminal 3 (B) - see below. In Configuration
Mode, set PuLLparameter to YESand, for Add/Subtract
operation, set InPuparameter to A-B.
NPN Open Collector
Contact Closure
Current Sink or
Line Driver
Bi-directional Quadrature Inputs
Connect Quadrature Encoder to V+ (Terminal 1), A input
(Terminal 2), B input (Terminal 3) and COM (Terminal 4) as
shown below. In Configuration Mode, set InPuparameter to
QuAd . For NPN open collector devices with no pullup
resistors, set PuLLparameter to YES .
IMPORTANT: In severe electrical noise environments, shielded cable is
recommended for inputs and outputs. Connect the shield only to the
building earth (ground).
Reset and Program Inputs
Connect Reset pushbutton or current sink device to Reset
(Terminal 5) and COM (Terminal 4). Connect Program
switch or jumper to PGM (Terminal 6) and COM
(Terminal 4).

Open Collector Output
Connect Terminals 12 (Preset 1 open collector) and 4 (COM) or 15
(Preset 2 Open Collector) and 13 (COM) to solid state devices as
below (upper circuit). To drive DC relay coils, connect Terminal 12
or 15 and V+ (Terminal 1) as below (lower circuit). Suppress
switching transients with a suppression diode, connected as shown.

Make cut-out(s) according to the details in
the diagram on the right. The maximum
panel thickness is 6 mm.
Rear face of mounting panel
Mounting bracket
Counter
housing
Tongues on mounting bracket
engage in ratchet slots on Counter housing
Insert the rear of the Counter housing
through the cut-out (from the front of the
mounting panel) and hold the Counter
lightly in position against the panel. Ensure
that the panel gasket is not distorted and that
the Controller is positioned squarely against
the mounting panel. Apply pressure to the
front panel bezel only. Slide the mounting
bracket in place (see right) and push it
forward until it is firmly in contact with the
rear face of the mounting panel (tongues on
the bracket should engage in matching
rachet positions on the Counter housing and
the mounting bracket springs should push
firmly against the mounting panel rear face).
CAUTION
Do not remove the panel
gasket from the Counter as
this may result in
inadequate clamping of the
Counter in the mounting
panel.

Relay Output
Connect AC or DC load circuits to Terminals 9, 10 & 11
(Preset 1) or 16,17 & 18 (Preset 2) (see below) as required.
Do not route load wiring near count input or transistor output
signals.

NOTE
To abort changes to a
parameter value, press
Down and Next together
instead of
ENT.
IMPORTANT
In Edit Mode, you must
press the
ENT key within
15 seconds of the last
keypress, otherwise the
new data will be lost and
the old data will be
restored.

Down key
Operator Mode:Used to change the
currently-selected (flashing) digit.
Depressing this key will decrement the
value (wrap-around from 0 to 9). If the
key is held continuously, the value will
decrement at the rate of 2/sec.
Program Mode: Used to advance from
one parameter to the next. Once a
parameter value has been selected for
editing (through use of the Next key),
depressing this key will decrement the
value (wrap-around from 0 to 9). If the
key is held continuously, the value will
decrement at the rate of 2/sec.
Configuration Mode:Used to advance
from one parameter to the next.
Next key
Operator Mode:Used to select a
parameter for editing (left-most digit will
start to flash) and to move between the
digits. Once the proper digit is selected
(flashing) with the Next key, its value can
be altered through use of the Down key.
Program Mode:Used to select a
parameter for editing (left-most digit will
start to flash) and to move between the
digits. Once the proper digit is selected
(flashing) with the Next key, its value can
be altered through use of the Down key.
For Decimal Point Position, this key
scrolls through the available choices.
Configuration Mode:Used to select a
parameter for editing and to scroll through
available choices.
ENT key
Operator Mode/Program Mode:
Confirms an edited value (display will
cease flashing after the ENTkey is
depressed).
Configuration Mode:Confirms
setting/value selection (display will cease
flashing after the ENTkey is depressed).
RST key
Operator Mode/Program Mode: Resets
count value to either zero or Preset value
(based on the setting of the Count
Direction parameter in Configuration
Mode). Also releases latched outputs.
Configuration Mode:Exits
Configuration Mode when held down for 2
seconds.
NOTE:The RSTkey will not be active
unless enabled in Configuration Mode.

Counter value
Preset 1 or Preset 2 value
The Operator Mode is used for viewing the
Count value and viewing/changing the Preset
1/Preset 2 value.
Press the Next key to enter Edit Mode.
The most significant digit of the Preset
Data display will then flash. Press the
Next key repeatedly as required to select
the desired digit.
Press the Down key to change the value
of the selected digit (there is wrap-round
from 0 to 9).
When all digits are as required, press the
ENTkey to confirm the changes; the
display will stop flashing.
IMPORTANT
You must press the ENTkey within 15
seconds of the last keypress when entering a
new value, otherwise the new value will be
discarded and the old value will be retained.
NOTE
To abort an edit
operation (before the
new value is confirmed),
press the Down and Next
keys together.
WARNING!
Caution should be
observed if it is
necessary to change
the preset value while
the process is
operating. Do not set
values which are
already exceeded by
the count value without
resetting the counter.

WARNING!
Changing Program
Mode parameter values
while the process is
operating may be
hazardous to the
operator and/or the
controlled equipment.
Use extreme caution
and stop the process
before attempting to
change Program Mode
parameter values.
IMPORTANT
You must press the ENT
key to implement new
parameter values.
NOTE
Possible Decimal Point
Position settings are:

To enter Configuration Mode,
power-down the Counter and
remove it from its housing. Change
the position of the lnk jumper on
the CPU PCB (the actual position is
irrelevant, as long as the position is
changed). Replace the Counter in
its housing and power-up. The PGM
indicator will flash whilst the
Counter is in Configuration Mode.
To exit Configuration Mode, either momentarily remove power from the Counter
or press and hold down the RSTkey for at least two seconds.
To edit a parameter, use the Down key to step through the parameters; when the desired
parameter description is shown in the upper display, press the Next key to enter Edit Mode and
to scroll through the available settings. When the desired setting is shown, press the ENTkey.
