Commissioning Procedure
Factory set default values
The measuring transducer features the following factory settings:
Limit value: Alarm 1: 3 ppm
Limit value: Alarm 2: 5 ppm
Delay of response: Alarm 1: 1 sec.
Delay of response: Alarm 2: 1 sec.
Actual value output: wire link 2 established = 0 - 20 mA
Seven-segment display without decimal point
Warning
The terminal strips of the measuring transducer are live during operation.
This presents the risk of electric shock.
Cut off power supply before opening the housing lid!
Before commissioning rinse the measuring sensor. Do not use caustic
agents for flushing unless the use of such agents is explicitly permitted by
the manufacturer.
Note
Adjust two different limit values if you want to use for instance alarm
contact 1 for a first alarm and alarm contact 2 for the main alarm.
For condensate and bilge water monitoring alarm contact 1 can then be
used to control a three-way valve, which will discharge the unusable
condensate if the level of turbidity is too high (alarm caused by ingress of
oil or start-up protection). Alarm contact 2 will trigger the main alarm / shut-
down.
Valves with single-phase A.C. motor, max. power rating 50 VA (see wiring
diagram on page 20, fig. 11) can be connected directly. If a three-phase
actuator is used fit a reversing contactor in between. Pneumatically
operated valves can be controlled via solenoid valves.
