Configuring the ECL 2000
EY.65.H4.02
33
Unit The Unit parameter is available when Sensor is set to Flow or to Energy. When Sen-
sor is set to Flow, the Unit parameter can be set as follows:
Value Description
l/h
Water flow is being measured in liter per hour
m
3
/h Water flow is being measured in m
3
per hour
Note:
When the flow unit is set to l/h, there is a risk of an overflow error if the measured
water flow exceeds 1024 l/h. This will lead to a blank flow reading on the
ECL 2000’s display. See the Technical Manual for the ECL 2000 LON Option (ref.
[4]).
When Sensor is set to Energy, the Unit parameter can be set as follows:
Value Description
kW Energy is being measured in kW. When this setting is active, the accu-
mulated energy is measured in MWh
MW Energy is being measured in MW. When this setting is active, the accu-
mulated energy is measured in GWh
Note:
When the energy unit is set to kW, there is a risk of an overflow error if the measured
energy (power consumption) exceeds 1024 kW. This will lead to a blank energy
reading on the ECL 2000’s display. See the Technical Manual for the ECL 2000 LON
Option (ref. [4]).
8.4.4 Relay Output
For some applications, you can also customize the ECL 2000’s relay output P3.
Function The relay output parameter Function can be set to the following values:
Value Description
Pump 3 The output controls a pump. This is the default setup for some applica-
tions
Timer
When this value is selected, one of the controller’s circuits is dedicated to
a timer function. The output is set to ON and OFF in accordance with the
7-day plan for the timer circuit. See also page 10.
Alarm The relay output is used as an alarm indication, i.e. the output is set to
ON and OFF in accordance with the ECL 2000’s Alarm Setup (see page
66).
