CONFIGURATION MODE
4.1 Introduction – Fig. 4.1
The Configuration Mode comprises two levels (3 and 4) as shown in Fig. 4.1.
Level 3 is divided into four frames. For most simple applications it is only necessary to
set up the parameters in the first frame.
Note.
When in the Configuration Level:
•

•
All the LED indicators flash.
All relays and logic outputs are turned off.
The analog output reverts to 0% (4mA) output level.

Note.
Process Alarms – an alarm becomes active when the process variable rises
above the high process alarm trip point value or falls below the low process
alarm trip point value. Process alarm trip point values are configured in
engineering units in Set Up Level (Level 2). If an alarm hysteresis value of
zero is configured the alarm becomes inactive when the process variable
value returns past the alarm trip point value. If a positive or negative
hysteresis value is configured the alarm becomes inactive when the process
variable reaches the hysteresis point. The hysteresis value is configured in
engineering units e.g. if a hysteresis point five inches H20 below the alarm
trip point is required, a hysteresis value of –5.0 is configured. The
programmable alarm hysteresis function can also be utilized for pump
control applications when an output relay is assigned to an alarm.

Note.
Fast/Slow Rate Alarms – an alarm becomes active when the rate of change in
the process variable is faster or slower than the configured alarm value. Rate
of change alarm values are configured as a % of span change per hour. The
elapsed time period before the alarm condition is detected is dependant
upon the configured alarm value. This period can be calculated as follows:
1800
t = 10.81 +
trip value (as a % of eng. span/hr)
t = 191 seconds
The alarm remains active until the rate of change in the process variable
returns to the non-alarm condition. The calculated time period (t) elapses
between the process variable reaching the non-alarm condition and the
alarm becoming inactive.

High/Low Latch Alarms – An alarm becomes active when the process variable
value rises above the high latch alarm trip point value or falls below the low
latch alarm trip point value. The latch alarm trip point values are configured
in engineering units in the Set Up Level (Level 2). The alarm remains active
until it is acknowledged and the alarm process condition is removed. The
alarm can be acknowledged using the keys on the instrument front panel
(see page 3) or via the volt-free digital input once it has been configured to
provide a remote alarm acknowledge facility.

EC Directive 89/336/EEC
In order to meet the requirements of the EC Directive 89/336/EEC for EMC
regulations, this product must not be used in a non-industrial environment.
End of Life Disposal
This instrument does not contain any substance that will cause undue harm to
the environment. It can therefore be safely considered as normal waste and
disposed of accordingly.
Cleaning
Clean the front panel only, using warm water and a mild detergent.

Notes.
DATUM L160
•
Sensor cable runs over long distances can
pick up transients which could impair
operation of the L160. Transient
protection within the L160 Level System
gives protection against induced voltage
transients of up to 2kV.

Warning.
•
The instrument is not fitted with a switch therefore a disconnecting device
such as a switch or circuit breaker conforming to local safety standards must
be fitted to the final installation. It must be mounted in close proximity to the
instrument within easy reach of the operator and must be marked clearly as
the disconnection device for the instrument
•
•
•
Remove all power from supply, relay and any powered control circuits and
high common mode voltages before accessing or making any connections.
Use cable appropriate for the load currents. The terminals accept cables up
to 14AWG (2.5mm2).
The instrument conforms to Mains Power Input Insulation Category 2,
Pollution Degree 2 (EN601010–1).
•
•
•
All connections to secondary circuits must have basic insulation.
After installation, there must be no access to live parts, e.g. terminals
Terminals for external circuits are for use only with equipment with no
accessible live parts.
•
•
If the instrument is used in a manner not specified by the Company, the
protection provided by the equipment may be impaired.
All equipment connected to the instrument's terminals must comply with
local safety standards (IEC 60950, EN601010–1).
Note.
•
Always route signal leads and power cables separately, preferably in earthed
(grounded) metal conduit.
•
It is strongly recommended that screened cable is used for signal inputs and
relay connections.
