This manual describes the installation of Durant clipse series digital ratemeter/
process timer models 5770X-47X. It begins with a description of the base unit and
the plug-in option boards. That is followed by mounting information, wiring diagrams,
and programming instructions. This manual concludes with diagnostic test and cali-
bration information and specifications. This device provides a rate or time readout
for the operator. Although the unit may be doing other functions as well, the only
thing the operator has to do with it is to observe the display.
DESCRIPTION
Base Unit
The clipse accepts a digital, pulsed signal from a sensor (that may be on an en-
coder, proximity or photo sensor, magnetic pickup, flowmeter, limit switch, etc.). It
calculates a rate or time, based upon the frequency of the input signal, to be dis-
played to the observer. The display can read in units of rate such as RPM, feet per
minute, barrels per hour, etc., or in units of time such as baking time or mold ma-
chine cycle time. In either case, the clipse employes the fiendishly clever Tau method
of calculation, which means that it very accurately times the period of the pulse
(Tau). Once Tau is known, the unit determines rate by the formula:
Rate = 1
Tau X Scaler
If the clipse is programmed to display process time, Tau is plugged into a slightly
different formula:
Process Time = Tau X Scaler
ither calculation requires that the installer program the unit with a scaler. The scaler
is a conversion factor that accounts for three conditions that are specific to the appli-
cation:
1. The units of time to be displayed, generally seconds, minutes, or hours.
2. The weight of each input pulse.
3. The resolution (decimal point location) of the display.
The installer calculates the scaler by using the appropriate formula below, depend-
ing upon whether the clipse should display rate or process time.
To display rate:
Scaler = NOS x DPF
PPI
,
where NOS = number of seconds in time unit (1 = seconds, 60 = minutes, 3600 =
hours, etc.).
INTRODUCTION / DESCRIPTION

DPF = decimal point factor. From the table below, select the DPF that matches the
display decimal point location:
Displayed Decimal Point D P F
XXXXX 1
XXXX.X 10
XXX.XX 100
XX.XXX 1000
X.XXXX 10000
And PPI = pulses per item, the number of pulses the unit receives from the sensor
per physical unit (revolution, foot, gallon, etc.) on the rate display.
To display process time:
Scaler = PPI x DPF
NOS
,
where NOS = number of seconds in the process time unit (1 = seconds, 60 = min-
utes, 3600 = hours, etc.).
DPF = decimal point factor, and is selected from the table above.
PPI = pulses per item, the number of pulses the unit receives from the sensor per
process cycle (oven length, mold machine cycle, etc.).
An inherent ability of devices that use the Tau method of calculation is that they can
calculate rate or process time and update the display each time an input pulse is
received. There is a practical limit to how fast the display should update, however,
especially when the process speed is changing and when there may be minor varia-
tions in pulse input frequency at a steady speed. The clipse has a programmable
display update time that sets the minimum time between updates. ach time the
display updates, the unit waits until the update timer times out and then updates the
display when the next pulse comes in. The clipse counts the number of pulses
received and times the total periods for all pulses received for each update. The
calculation averages Tau for all periods in the update effectively smoothing out the
display. The installer programs an update time in the range of 0.1 to 99.9 seconds to
obtain a display that is smooth, yet responsive.
Sooner or later, the process being monitored will be brought to a halt. Pulses will
stop coming in from the sensor. What happens once the update timer has timed out
and the clipse is patiently waiting for the next pulse to come in so that it can update
the display, but the next pulse is not coming? Like the bride who has been stood up
at the altar, something must tell the clipse that it is waiting in vain and it is time to
get on with its life. The clipse is equipped with a zero timer for this purpose. The
zero timer sets the units patience between pulses. The installer programs a zero

time in the range of 0.1 to 99.9 seconds. Should the time between pulses ever ex-
ceed the zero time, the clipse will immediately update the display to zero, whether
in rate or process time mode.
Relay Output Option Board
The optional relay board contains two form C (normally open and normally closed
contacts) relays. ach relay has an adjustable high and low setpoint. The relays act
as alarms by turning ON when the displayed rate or time is greater than the high
setpoint OR less than the low setpoint. If the low setpoint is greater than the high
setpoint, the relay turns ON when the rate or time meets both conditions; less than
the low setpoint AND greater than the high setpoint.
Once a relay turns ON, it stays ON until the rate or time returns back across the
setpoint and then some. The and then some is called hysteresis. Hysteresis is a
programmable value that is common to both setpoints and both relays. This means
that a relay turns OFF when the display is less than or equal to the high setpoint
minus the hysteresis value, or when the display is greater than or equal to the low
setpoint plus the hysteresis value. Should an overlap occur between ON and OFF
conditions, the ON condition overrides the OFF condition.
xample: Relay Output Operation
High Setpoint = 250 Relay ON above 250
Low Setpoint = 220 Relay ON below 220
Hysteresis = 10 Relay OFF between 230 and 240

Analog Retransmission Option Board
The optional analog output board provides linear 0-10 V and 4-20 mA signals pro-
portional to the displayed rate or time. When the displayed value is equal to the
programmed output offset value, the output voltage is zero and the output current is
4 mA. When the displayed value is equal to the programmed output full scale value,
the output voltage is 10 V and the output current is 20 mA.

When the displayed value is between the output offset and output full scale value:
1. The output voltage = 10 (displayed rate - offset value)
(Full scale value - offset value)
V,
2. The output current = 16 (displayed rate - offset value)
(Full scale value - offset value) mA + 4 mA
RS 85 Serial Communications Option Board
The optional serial communication board allows a host device to download and read
programming parameters and to read status information from the rate meter, such
as display value, relay status, etc.
This manual does not contain information on the serial communication protocol or
the serial command list. That information is contained in the 57700 serial specifica-
tion and is obtainable by contacting the Durant Literature Department at 800-540-
9242 (U.S. and Canada), or 920-261-4070, or by FAX at 920-261-9097.

WIRING
All wiring to the ratemeter is done via rear terminal, de-pluggable connectors. Up to
five headers accept the wired connectors on the ratemeter. All units have at least two
headers, power input and signal input. Any combination of three additional circuit
boards with headers may be installed. These option boards are relay output, RS 485
serial communications, and analog retransmission. The option boards occupy spe-
cific locations in the ratemeter and are not interchangeable.

WIRING
Disconnect all power before wiring terminals. A safety hazard exists if this
precaution is not observed. Treat all signal inputs as hazardous since
they may carry line voltage.
A switch shall be included in the building installation:
 It shall be in close proximity to the equipment and within easy reach of the
operator.
 It shall be marked as the disconnecting device for the equipment.
 Switches and circuit breakers in urope must comply with I C 947.
Terminal Connector Ratings
AC or DC Power Input / Relay Output: 10A, 250VAC;
Wire size: 12-24AWG (3.1mm2 - 0.24mm2), 600V.
RS485 / Analog Output / Signal Input: 8A, 125VAC;

General Wiring Practices
 Use shielded cables for signal and control inputs.
 Keep all signal lines as short as possible (<30M or 100 ft.).
 Do NOT bundle or route signal lines with power or machine control wiring.
 Do not allow signal or control wires to leave the building.
