Control direction S1/S2
By default, the control direction is set to exceeded (=
downwards) for S1, and for S2 it is set to upwards.
This means that if the value set for setpoint S1 is
exceeded, relay 1 is switched, and if the value drops
below setpoint S2, relay 2 is switched.
It is possible to change the control direction for S1
and S2.
Ctrl. direction
Upward control
1. Press the [Right] button to open the
"Ctrl. direction S1" or "Ctrl. direction S2" menu.
2. Press the [Up] and [Down] buttons to set the
value.
Hysteresis
The hysteresis setting only takes effect for a limit
value. If a setting is made, the hysteresis band
surrounds the selected setpoint symmetrically. If the
setpoint S1 is set to 0.500 mS and the hysteresis
setting is set to 0.010 mS, the relay switches on or
off (depending on the control direction) at 0.505 mS
and 0.495 mS.
Hysteresis
0.010 mS
1. Press the [Right] button to open the "Hysteresis"
menu.
2. Press the [Up] and [Down] buttons to set the
value.
Intermittent pulse period
The factory setting for the intermittent pulse period is
10 seconds. This setting has proved ideal for nearly
all applications.
Int. pulse period
10 sec.
1. Press the [Right] button to open the "Int. pulse
period" menu.
2. Press the [Up] and [Down] buttons to set the
value.

Minimum impulse/minimum switch-on time
The minimum switch-on time determines the shortest
drive pulse in the intermittent pulse period
regulation.
The intermittent pulse period setting must always be
at least twice as long as the minimum switch-on
time.
Min. switch-on
0.5 sec.
1. Press the [Right] button to open the
"Min. switch-on" menu.
2. Press the [Up] and [Down] buttons to set the
value.
12.4.3 Switch-on delay
If the switch-on delay of the Conex
activated, the controller is not activated until the
specified time has elapsed after the power supply to
the device has been switched on. This menu can be
used to switch the switch-on delay on and off, and if
the switch-on delay is activated, the delay duration
can be entered.
Contr. param.
Delay ctrl.
Activating/deactivating the switch-on delay
1. Press the [Right] button to open the "Delay
control" menu.
Delay ctrl.
On
2. Press the [Right] button to switch between on
and off.
Setting the switch-on delay time
1. Press the [Right] button to open the value input
display.
2. Press the [Up] and [Down] buttons to set the
value.
