This is done in setpoint menu no. 15. If this setpoint is set to
”0”, the ES10 will maintain a
constant air pressure (measured in Pa, Pascal). If the setpoint is set to
”1”, the ES10 will
maintain a constant air flow (measured in m/s, meter per sec).
The 3 operation mode setpoints described below changes automatically between Pa and
m/s depending on the selected operation mode.
ES10 comes with 4 different operation modes:
1) Off mode. The ES10 is off, and there is 0VDC on the motor output (cl12,13) and the
motor relay (cl16,17) is open. In off mode the alarm surveillance is not active.
2) Day mode. The ES10 is adjusting in accordance with the day mode setpoint. This is set
in setpoint menu no. 1. This setpoint is adjustable from 0Pa to 5000Pa (in air pressure
adjustment mode) or from 0.00m/s to 50.00m/s (in air flow adjustment mode).
The motor relay (cl16,17) is closed and the motor output (cl12,13) receives a voltage signal.
In day mode the alarm surveillance is active. See alarm description in section 3.4.
3) Night mode. The ES10 is adjusting in accordance with the night mode setpoint. This is
set in setpoint menu no. 2. This setpoint is adjustable from 0Pa to 5000Pa (in air pressure
adjustment mode) or from 0.00m/s to 50.00m/s (in air flow adjustment mode).
The motor relay (cl16,17) is closed and the motor output (cl12,13) receives a voltage signal.
In night mode the alarm surveillance is active. See alarm description in section 3.4.
4) Max mode. The ES10 is adjusting according to the max mode setpoint. This is set in
setpoint menu no. 3. This setpoint is adjustable from 0Pa to 5000Pa (in air pressure
adjustment mode) or from 0.00m/s to 50.00m/s (in air flow adjustment mode).
The motor relay (cl16,17) is closed and the motor output (cl12,13) receives a voltage signal.
In max mode the alarm surveillance is partially activated, as the surveillance does not alarm
at ”too low pressure”. See alarm description in section 3.4.
In setpoint menu no. 23 it is possible to set the max mode input (cl8,9) to operate inverted.
If this setpoint is set at 0, the ES10 goes into max mode if cl8,9 is shortened. If the setpoint
is set to 1, the function is inverted.

3.4 Alarm control
The ES10 is equipped with 3 different alarm modes:
1) Motor error alarm. If the connection between clamps 14 and 15 is disconneted, the
display will show
”ERROR! motor”, and the alarm relay will change state (Clamps 18, 19,
