Setting and activating the outputs with menu commands
Disconnect the security lock jumper!
• Select MORE in the main menu and then ALARM; the following
is displayed:
• If the settings need to be changed, press CL:
- the quantity starts blinking; it can be changed with arrow switches,
and acknowledged with ENT.
- the third parameter (in this example HI ON) starts blinking. This
parameter determines whether the alarm output is in use or not, and
when it is activated. Select the output control state with the arrow keys.
The selection is acknowledged with ENT.
The options are the following:
- HI ON (the alarm is activated by exceeding the setpoint, the output
is in use)
- LO ON (the alarm is activated if the value goes below the setpoint,
the output is in use)
- HI OFF (the alarm is activated by exceeding the setpoint, the output
is not in use)
- LO OFF (the alarm is activated if the value goes below the setpoint,
the output is not in use)
- The setpoint starts blinking (in this example, -20.00); if you wish to
change it, press CL. Use the arrow keys to select the new setpoint digit
by digit and acknowledge each digit using the ENT key. Using the CL
key, you can correct the entry by deleting the digits one by one. When
you have entered the whole setpoint, press ENT for the second time.
- The hysteresis value starts blinking (in this example, 5.00); if you wish
to change it, follow the instructions given in previous paragraph.
NOTE
The options HI OFF and LO OFF are used to deactivate the relay
outputs e.g. for service purposes.
The settings of the channel 2 are changed in the same way.
