Eagle Signal Series B856 Instruction 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-perdigit interface.

It can be easily programmed to perform any standard timing operation: On-Delay, OffDelay, 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.

An available model's output features separate timed and instantaneous SPDT contacts.

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.

Technical Manual 702070-0001

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 11 pin socket and a power supply that can accept 24 - 240 VAC or 24 VDC vastly simplify setup.

Start

Socket

Power

To wire the unit, an 11 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.

FRONT PANEL OPERATION

I/O Status Indicators

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.

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.

Time Value

Indicates the elapsed/remaining time to preset.

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.

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.

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

H M S

Minutes:Seconds.

Set Value

Settable value used to trigger the timed output.

Numeric Keys

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).

PROGRAMMING

PROGRAM MODE

• Enter the Program Mode by holding down the "P" key for 3 seconds

• Press the "P" key to move the top display from one parameter to the next

• Press the "E" key to scroll the bottom display through the available choices for that parameter

• While in Program Mode the unit will stop timing, and the output will retain its last state. The new settings will only become effective after returning to Operation Mode by holding down the "P" key for 3 seconds

For 3 Seconds

Operating Function: Determines how outputs will operate in relation to the set value. Choices are:

Func

OndL

See Appendix A for timing charts.

• On-Delay (OndL)

• Off Delay (OFdL)

• Interval 1 (int1)

• Interval 2 (int2)

• Delay/Interval (dint)

• Repeat Cycle (CYCL)

First Operation: Determines whether the Repeat Cycle will start with an On or an Off Operation

Note: This parameter will only appear if Repeat Cycle is chosen as the Operating Function

Interval Time: Sets the amount of time the output will be active after the On-Delay function has timed

out. Use the 1 through 4 keys to set the value in a range from 0.1 to 999.9 seconds.

Note: This parameter will only appear if Delay/Interval is chosen as the Operating Function

Time Range: Sets the unit of measure for the time values that will be shown on the display in

Operation Mode. Choices are:

• Seconds

• Minutes

• Hours

• Minutes:Seconds

• Hours:Minutes

Decimal Position: Sets the decimal position for the time display. Choices are: no decimal point (0), 1/10ths position (0.0), or Hundredths position (0.00). The time range selected in the previous parameter will remain illuminated for reference.

Note: This parameter will not appear if Minutes:Seconds or Hours:Minutes is selected as the time range
