Eagle Signal B856-501 User manual

Introduction
An excellent value in its class, the B856 features a compact 1/16 DIN package, the
precision of digital setting, versatile functionality, and a straightforward button-per-
digit interface.
It can be easily programmed to perform any standard timing operation: On-Delay, Off-
Delay, Interval 1, Interval 2, or Repeat Cycle. A unique On-Delay /Interval Mode can in
many cases perform the function of two separate timers. Output is via DPDT relay
contacts.
Five selectable time ranges and a programmable decimal point provide preset times
ranging from .01 seconds to 9999 hours.
Simplicity of operation is maintained while still providing a high level of functionality. All
programming is done through the front panel, with an intuitive button-per-digit keypad
that makes entry of preset times quick and easy. A crisp dual line LCD display lets the
operator readily view elapsed or remaining cycle time as well as the preset value.
Prominent annunciators indicate
information such as the time range and the
status of the input and outputs.
Reliability is a key feature of the B856. IEC
Level 4 noise immunity ensures flawless
operation in harsh electrical environments,
while its IEC IP65 enclosure rating allows
use in washdown conditions.
Wiring via an industry standard 8 pin
socket and a power supply that can
accept 24 - 240 VAC or 24 VDC vastly
simplify setup.

Time Range Indicator
Illuminates to show the time base: H for
hours, M for minutes, S for seconds.
Multiple indicators will be illuminated
when the time base is Hours:Minutes or
Minutes:Seconds.
Program Key
Pressing the key continuously for 3 seconds moves the unit in and
out of Program mode. Once in Program mode, pressing and
releasing the key will scroll the display from one parameter to the
next.
Edit Key
Many of the parameters in Program Mode require selection of a
specific choice as opposed to a numeric value. The Edit key is
used to scroll through the available choices. In Operation mode,
the Edit key can be pressed simultaneously with the Program key to
reset the timer.
Each of the number keys is used to
increment or decrement the value of the
corresponding digit of the preset or a
parameter value (increments if unit is set
in time up mode and decrements if set in
time down mode).
Numeric Keys
Set Value
Settable value used to trigger the timed
output.
Time Indicators
The word "Timing" Flashes when a timing
function is taking place. The applicable
arrow also lights to indicate if the display is
set to time up or time down.
Illuminates to display when an input or
output is active: "IN' for the start input,
"OUT" for the timed output, and "RST" for the
external reset signal.
I/O Status Indicators
Indicates the elapsed/remaining time to
preset.
Time Value
To wire the unit, an 8 pin socket is required. The unit
can then either be DIN rail mounted or panel mounted
using the supplied mounting bracket. For panel
mounting, place the unit in the cutout, then slide the
bracket forward over the rear of the unit so that the
tabs catch in the grooves on the housing and the
bracket is as far forward as possible. Tighten the
panel mount screws until there is a snug fit against
the panel. Do not overtighten.

Timing begins on the leading edge of the start input. The output will activate
at the completion of the preset time (T) and will remain active until the reset
signal is applied or power is interrupted.*
The output is activated at the leading edge of the start signal. Timing begins
on the trailing edge. The output will remain active until the preset time (T) has
elapsed or power is interrupted.* Reapplying the start signal before T has
elapsed will reset the time value. The reset input is not used.

RepeatCycle
Timing begins on the leading edge of the start signal. A cycle is initiated
where the output will be OFF for the preset time (T), then ON for the preset
time. This cycle will continue until a reset signal is applied or power is
interrupted,* The unit can also be programmed for the timing sequence to
begin with an ON cycle.

Delay/Interval
The delay cycle begins upon application of the start signal. The output will
activate at the completion of the preset time (T1). Upon activation of the
output, the Interval cycle will begin. The output will be deactivated at the end
of the Interval time (T2). T1 is the primary preset value and is set in Operation
Mode. T2 is set in Program Mode in a range from 0.1 to 999.9 seconds. The
timing sequence and output can also be reset through the reset input or
interruption of power.*
* The Power Reset parameter in Program Mode can be set so that a timing
sequence will not be reset upon power interruption but instead continue
on when power is restored.
