The internal clock (see Section 2.3.4.2) provides the date and time unless the
battery (see Section 2.3.4.1) is disconnected.
3.2.3
Relay Setup
3.2.3.1
Relay Test
The
Relay Test
parameters are used to set the operation mode of each of the five
relays. The four operation modes are explained in Section 6.5.3.
3.2.3.2
Relay#1 Setup to Relay#4 Setup
These four options display all alarm conditions assigned to a relay. They are used
to assign new alarms, or to remove some, to each of the four alarm relays.
Individual alarm conditions can also be assigned to a relay through parameters
Alarm L-L Relay
,
Alarm
Low Relay
,
Alarm Hi Relay
and
Alarm Hi-Hi Relay
from
Alarms > Alarms Setup
(see
Section 3.3.2).
3.2.4
Temp Setup
The
Temp. Setup
parameters pertain to the operation of the Hydran M2-X
’s
heater plate and dynamic oil sampling system.
•
Temp Set Point
: Set point of the sensor temperature (average target
temperature of the
heater plate). The default value is 35 °C.
•
Temp SP Modulation
: Temperature variation around the
Temp Set Point
. For
example: if
Temp Set Point
is set to the recommended temperature of 35 °C
(95 °F) and
Temp SP Modulation
to 10 °C (18 °F), the temperature varies
between 30 and 40 °C
(86 and 104 °F).
•
Temp Mod. Period
: Modulation period of the temperature variation. If
Temp
Mod. Period
is set to 120 minutes (default value) in the above example; it
takes 120 minutes
for the heater plate temperature to go from 35 to 40 to 35
to 30 to 35 °C (from 95 to 104 to 95 to 86 to 95 °F).
For more information on the dynamic oil sampling system, see Section 2.5.
3.2.5
Calibration
The
Calibration
function is used to calibrate the following analog inputs:
•
The gas sensor signal.
•
The moisture sensor signal.
•
The thermistor in the sensor.
•
The thermistors in the heater plate.
