FW-E018-P-M_v0203_03_EN.docx
Page 6
Standard outputs
▪Configurable pulse output to transmit pulses representing a certain linearized total quantity. The
pulse length can be set as desired with a maximum frequency of 500Hz for output R1 and R2
and 4Hz for output R3 and R4..
▪Unscaled frequency output for retransmission of the incoming pulses as robust square wave
forms.
▪Up to 4 configurable alarm outputs: flow rate alarm, high-, low-, high-high- or low-low-flow rate
alarm. Switched as long as the flow rate is too high or too low.
▪Configurable linear 4-20mA isolated analog output with 12-bits resolution representing the actual
flowrate.
Flowrate levels as well as the minimum and maximum signal output can be tuned.
Configuration
The E018-P has been designed to be implemented in many types of applications. For that reason, a
SETUP-level is available to configure your E018-P according to your specific requirements.
It includes several important features, such as K-Factor, measurement units, signal selection etc.
All settings are stored in an EEPROM memory and will not be lost in the event of a power failure or a
drained battery.
To extend the battery-life time, please use of the power-management functions as described in
chapter 3.
Display information
The E018-P has a large LCD with all kinds of symbols and digits to display measurement units,
status information, trend-indication and key-word messages.
Flowrate and totals can be displayed either with the 11 small 7mm (0.28”) digits or with the 7 large
12mm (0.47”) digits. Additionally, the E018 has an analog speedometer to show the actual flowrate.
Backlight
A backlight is standard available. The intensity can be set as desired (externally powered only).
The backlight can even be used in battery powered applications: it will be switched on, at a fixed
intensity, during a limited period of time and will switch off automatically, 3 seconds after a key touch.
For loop powered applications only, the backlight will not come on because of limited power.
Options
The following options are available: mechanical relay, power- and sensor-supply options.

2 OPERATIONAL
2.1 GENERAL INFORMATION
This chapter describes the daily use of the E018-P. This instruction is meant for users / operators.
•The E018-P may only be operated by personnel who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed
•Take careful notice of the “Safety rules, instructions and precautionary measures” in the
front of this manual.
2.2 CONTROL PANEL
The optical keys are operated through the glass. The following keys are available:
Fig. 2: Control panel, optical keys
Functions of the keys
PROG-key
This key is used to program and save new values or settings.
The PROG-key is also used to gain access to SETUP-level; please read chapter 3.
SELECT-key
This key is used to SELECT the displayed information, like accumulated total and
flowrate.
CLEAR-key
This key is used to CLEAR the value of total.
The CLEAR-key also provides access to historical day totals (or optional data logging).
Use of optical keys
The optical keys are designed to operate stable and will not be activated when the glass surface is
not clean. However, keep the glass surface clean to avoid false key activations (false activations
reduce battery lifetime). Also do not mount objects within 100mm in the front of the product (shiny
surfaces could cause false activations). It is not necessary to touch the glass for activation.
Activating by touching the clean glass surface normally also works fine, but in case of detection
problems try not to touch the glass.
Unlock / lock optical keys
To prevent any undesired operation of the optical keys and to save battery power, an automatic key-
lock function is implemented. This function can be disabled at SETUP-menu Others.

FW-E018-P-M_v0203_03_EN.docx
Page 8
When the optical keys are locked, the key lock symbol is shown at the top of the display as
shown below.
Fig. 3: Control panel, disable optical keys
To unlock the optical keys, the operator need to ‘activate’ the keys by pressing any of the keys for
about 1 to 2 seconds. After activation, the backlight will light up (if enabled) and the display will hint
the following sequence of keys for the operator to briefly touch after each other:
PROG –SELECT –CLEAR
When the sequence is successfully executed, the optical keys will be unlocked and the key lock
symbol will disappear.
The optical keys are automatically locked after 30 seconds of inactivity. However, to lock the optical
keys manually, touch the PROG and CLEAR key simultaneously for 3 seconds.
Enable or disable optical keys with on-off switch
Directly below the optical keys an on-off switch is located to enable or disable the optical keys. Move
this switch to the right to enable or to the left to disable the optical keys. When the optical keys are
disabled the key lock symbol will appear in the display and operation of the unit can only be
performed with the mechanical push buttons.
Fig. 4: Control panel, ON/OFF optical keys
For battery powered applications it is recommended to switch off the optical keys when
possible to save on power consumption significantly.
Push button operation
Next to the three optical keys also three push buttons are available when the cover is removed.
Make sure the key lock is active before removing the cover to prevent unwanted actions.
On the side of the collar of the display three black mechanical push buttons are present in the same
order as the optical keys, PROG –SELECT –CLEAR. They operate in the same manner as the
optical keys, and when pressed, the optical keys are disabled for 30 seconds to prevent any
interference.

2.3 OPERATOR INFORMATION AND FUNCTIONS
Be aware that the optical keys may be locked and will not function.
Unlock the optical keys as described before.
By default, the E018-P will act at Operator level. The information displayed is dependent upon the
SETUP-settings. Signals generated by the connected flowmeter are measured by the E018-P in the
background. The display values are however updated depending on the selected refresh rate. After
pressing a key, the display will be refreshed 8 times per second, after 30 seconds it will return to the
selected setting.
Fig. 6: Example of display information during process
For the Operator, the following functions are available:
Display process values
On the main screen, the primary process values of the E018-P are shown. By default, Total is shown
on the upper-line of the display and Flowrate on the bottom line.
In the configuration settings for Display, this can be changed to show only Flowrate on the large
12mm digits or to show Total and Accumulated Total simultaneously. When Flowrate is shown, the
arrows ▲▼ indicate the trend (increase or decrease) of the flowrate.
By pressing the SELECT-key, the operator can scroll through the screens showing the various
process values. After 30 seconds of inactivity, the display will automatically return to the main
screen.
The following table shows the available information:

Flowrate alarm indications
When the flowrate monitoring function is enabled and high or low flow is detected,
the alarm-flag is shown on the display and the information on the bottom line will
toggle between the normal information and an indication of the flowrate alarm
(e.g. LO-LO ALARM).

Clear total
The value for Total can be cleared and reset to zero. This action does not influence the value of
Accumulated Total or Current Day Total.
To clear Total, press the CLEAR-key when Total is shown on the display and the display will show
the flashing text “PUSH CLEAR”. When the CLEAR-key is pressed a second time, Total is set to
zero. To avoid clearing Total at this point, press the PROG- or SELECT-key or wait for 20 seconds.
•If the ‘Total CLEAR password’ is set in the configuration settings for Total, the operator is
asked to enter the password before the “PUSH CLEAR” text is shown. The correct
password needs to be entered before Total can be cleared. (See paragraph 3.2.3.)
•The IB option (external reset) allows clearing of total via an external pushbutton. This
clear action operates in parallel with the clear action via the control panel but does not
require any extra confirmation or password. When the external connection is permanently
closed, Total still counts but the ”Clear Total” function via the control panel is disabled.
Display flowrate
Internally, the flowrate is calculated up to 8 times a second, To obtain a readable value, the flowrate
shown on the display is updated once every second. Flowrate is shown, based on the configuration
settings for Flowrate, with the configured number of decimals. The configured unit and time unit are
indicated on the bottom line of the display.
When “-------“ is shown, the flowrate value is too high to be displayed. The arrows ▲ and ▼indicate
the trend (increase or decrease) of the flowrate.
Display total and accumulated total
A resettable Total and non-resettable Accumulated Total are available. The Total value can count up
to 9.999.999 before rolling over to zero; the Accumulated total can count up to 99.999.999.999
before rolling over.
The unit and number of decimals are displayed according to the configuration settings for Total.
Display speedometer flowrate
Along the edge of the display, a percentage based impression of the actual flowrate is shown. The
speedometer consists of 20 segments which run from 0 to 100% in increments of 5%. This function
can be enabled or disabled in the SETUP-menu Display.
2.4 OPERATOR ALARMS
Low-battery alarm (Type PB only)
During operation the battery voltage drops. When the battery voltage becomes too low, the battery
indicator comes on to show that the operation and indication become less reliable. When the battery
indicator is on, install a fresh and new battery (as soon as possible) to keep a reliable operation and
indication.
Fig. 7: Example of low-battery alarm
