PD6830 Pulse Input Rate/Totalizer Instruction Manual

INTRODUCTION

The ProtEX-RTP PD6830 is a rugged, explosion-proof pulse input rate/totalizer fully

featured for demanding applications in hazardous areas or in the harshest

environmental conditions. It is programmed using the four SafeTouch®through-glass

buttons, without removing the cover. The numeric rate display will read up to 99999

and the alphanumeric total/tag display will read up to 9999999. The alphanumeric

display can also be programmed to show any combination of numbers and letters up

to seven characters long for use as engineering units and/or the process

identification tag. The backlight makes the display more visible under any lighting

condition. The enclosure is provided with threaded conduit holes and integrated pipe

or wall mounting slotted flanges.

LOW-FLOW CUTOFF 0-99999 (0 disables cutoff function)

DECIMAL POINT Up to five decimal places or none:

d.dddd, d.ddd, d.dd, d.d,or dddddd

CALIBRATION May be calibrated using K-Factor, scale without signal

source, internal calibration, or by applying an external

calibration signal.

K-FACTOR Field programmable K-Factor converts input pulses to rate in

engineering units. May be programmed from 0.000001 to

9999999 pulses/unit.

CALIBRATION

RANGE Input 1 signal may be set anywhere in the range of the me-

ter; input 2 signal may be set anywhere above input 1 set-

ting. Minimum input span is 1 Hz.

An Error message will appear if the input 1 and input 2

signals are too close together.

DEBOUNCE FILTER Programmable contact debounce filter: 40 to 999 Hz maxi-

mum input frequency allowed with low speed filter.

TIME BASE Second, minute, hour, or day

GATE Low gate: 1-99 seconds; High gate: 2-999 seconds

Rate/Totalizer

DISPLAY

ASSIGNMENT The top display is assigned to rate. The bottom display is

programmable to alternate between total for 10 seconds,

then the tag for 2 seconds or to show only the total or to

show only the tag.

TOTAL

DECIMAL POINT Up to six decimal places or none:

d.dddddd, d.ddddd, d.dddd, d.ddd, d.dd, d.d or

ddddddd

Total decimal point is independent of rate decimal point.

TOTALIZER Calculates total based on rate and field programmable mul-

tiplier to display total in engineering units. Time base must

be selected according to the time units in which the rate is

displayed.

TOTAL RESET Via SafeTouch

RESET button, mechanical button (cover

off), external contact closure, automatically via user select-

able preset value and time delay. Manual reset may be

disabled or protected by password.

TOTALIZER

ROLLOVER Totalizer rolls over when display exceeds 9,999,999.
