Introduction
Your V eeder-Root brand C628 Elapsed Timer is one model in a family of 1/8 DIN units
which offers breakthrough display technology as well as easy-to-program single-line
parameters. Designed to provide instant visual feedback regarding an application’s key
input value, the C628 not only has a 0.71” high LED display (27% larger than other 1/8
DIN units), but also the ability to change display color based on process status
(programmable parameter in Operation Mode). Easy programming is made possible via a
help function and a secondary legend display.
This manual will guide you through the installation and wiring of your C628 unit with
information on proper panel mounting and rear terminal layout and wiring instructions.
In addition, the instrument’s operation and programming modes are thoroughly
explained. The Operation Mode provides day to day operation and allows editing of
preset values. The Program Mode enables the configuration of various parameters prior
to initial operation. These parameters include those for basic configuration as well as
other settable features which will enhance the functionality and usability of the device.
This manual also provides
information on the C628
Elapsed Timer’s transistor and
relay outputs, product
specifications, and ordering
and warranty procedures.

SIZE
The instrument can be mounted in a panel with a thickness of up to 6mm. The
cutout(s) should be made based on the recommended panel opening illustrated in the
drawing above.
Insert the unit in the panel through the cutout. Ensure that the
panel gasket is not distorted and the instrument is positioned
squarely against the panel. Slide the mounting clamp into place
on the instrument, as shown to the left, and push it forward until
it is firmly in contact with the rear face of the mounting panel and
the tabs on the bracket arm are seated in the mounting grooves
on the side of the unit.

The electronic components of the instrument can be removed from
the housing after installation without disconnecting the wiring.
To remove the components, grip the side edges of the panel and
pull the instrument forward. Take note of orientation of the unit
for subsequent replacement in the housing.

transistor output.
A contact closure or NPN signal can be used to activate preconfigured
functionality. Terminal # 5 is used for a remote reset function, while
Terminal #6 is a security function, that when active, will prohibit entry
into Program Mode. Terminal #8 serves as the common for both of these
inputs.
Relay Outputs
Your unit comes standard with a relay output which is tied to the Set
V alue. Terminal #19 is NC, Terminal #20 is common, and Terminal #21
is NO.
Auxiliary Power Output
A 9 - 15 VDC for powering external sensors up to 125 mA can be
accessed by connecting the positive supply side of the sensor to Terminal
#4 and the negative side to Terminal #8.
Serial Communication
An RS-485 communication board, utilizing ASCII protocol, can be
installed as an option. Terminals #16 & #17 serve as the B and A
connections respectively, while Terminal #18 is connected as the
common.
Input Power
For an AC powered unit, Terminal #13 serves as the line or Hot side
connection for AC powered units and as the positive side for DC powered
units. The neutral side for AC powered units and the negative side for
DC powered units are connected to Terminal #14.
Terminals 1, 9, 10, 11, 12, 15, 22, 23, & 24
are not used.
