The scaling of AI1
It is possible to choose between 2 types of mA measurements. Either "0-20 mA" or the most common "4-20
mA". Min./Max. scaling points is entered at the desired resolution. For example, if a pressure transmitter
with a measuring range of 0-5m is used, and you need to read the level in cm. Enter min. = 0 and max. =
500.
Limit relay values
Limit relay values can be configured for high/low limit levels. For both types of limits the function can be
activated/deactivated, and the limit relay can be named with a label used as text in an alarm list and in SMS
alerting.
Values can be set to which level the high/low limit relays are activated, and a delay can be attached, so that
a limit value must be exceeded for a given time before the signal is registered as active. It is possible to
choose whether to send the signal as an alarm or to act as a local alarm.

Functions for I1-6:
Standard DI function: Can be used to count pulses or check the state of a desired digital signal.
Standard VI function (0-10V): Can be scaled, the scaled value can be displayed. High/low limits are
attached to the signal, which can trigger an alarm if the limits are exceeded.
Klixon for P1/P2: Used in connection with pump control where the input can be configured as an alarm
signal that stops the faulty pump. The state of Klixon can be read in the Pump Status word on bit 2.
Thermal error P1 / P2: Used in connection with pump control, where the input can be configured as an
alarm signal that stops the faulty pump. The state of the Thermo relay can be read in the Pump Status word
bit 1.
High-level switch: Used as a start signal for emergency control of the pumps in case of faulty level
transmitter. The state of the high-level switch can be read on the Spider status word bit 26.
Pump running P1/P2: used as feedback signal for the pump control. If the corresponding output on SPIDER
is drawn, but the operating signal fails for more than 1 min. the pump is stopped. The state of the operating
signal can be read in the pump status word at bit 0.
Power measurement P1/P2: Used as an operating feedback. If the corresponding output on SPIDER is
drawn, but "low limit" is still indicated for more than 1 min. the pump is stopped. The state of the operating
signal can be read in the pump status word at bit 0.
Manual mode P1/P2: Disables the auto function for the pump when the signal is active. The signal typically
comes from an “Auto-0-Man” switch. The condition of “out of auto” can be read on the pump status word
bit 3.
IO expansion: Can only be used on I1 and I2, thus increasing the number of digital inputs up to 12. On the
additional Digital inputs, the following functions can be selected: Standard DI, Klixon, Thermal error, pump
running, manual mode and high-level switch.
Intensity: used in relation to rain gauges, where you can read the following values: Total counts of pulses,
today counter and yesterday counter. The values can be read on reg. adr. 256, 258, 260. At each pulse on
the input, the value increases with the entered value for VI settings - Maximum Scaling.
PIR: stands for Passive InfraRed sensor. This feature is typically used with a digital output that has the “Fan”
function. When the PIR input is activated, the fan starts up and runs for a specified time.

19
Heat sensor: Typically used with a digital output that has the function "Heat control". The input typically
has a heat sensor fitted which gives a 0-10V output signal. The input is scaled according to what 0V and 10V
correspond to. This defines a low limit at which the heat control must be activated and a high limit at which
heat control is deactivated.
Valve opened: Used with a digital output that has the function "Open valve", the function is used with
another set of DI/DO, where you can open and close a valve that stops the supply to the pump well,
whereby the inlet pipes can be used as reservoirs in case of increased inflow/rain event etc.
Valve closed: Used in conjunction with a digital output that has the "Close valve" function. Read the
description above.
General stop: Used as a general stop function. If the digital goes high it stops the pumps. Can be used in
case of “dry running”of pumps, where a mechanical stop is activated and stops the pumps.
Digital output
DO 1-2 are relay outputs dedicated to pump control, where DO 3-4 is used for specialized functions.
To configure DO 1-4 click on the button shown below the
Spider image.

Functions for DO 3-4:
Not used: The digital output has no function associated, so the output can be used freely and can be
controlled from SCADA.
Pump 1 (mirror): The output is triggered when P1 is running but is subject to its own delay, if selected, on-
timer.
Pump 1 error: The output is high if P1 is faulty.
Pump 2 (mirror): The output is triggered when P2 is running but is subject to its own delay, if selected, on-
timer.
Pump 2 error: The output is high if P2 is faulty.
General alarm: The output is high if an active alarm is registered in the SPIDER.
Compressor function: The output can be configured to activate a compressor after the pump run has
ended, and it can be selected whether the compressor should run intermittent operation or whether it
should only be activated once after the pump run has ended.
For interval operation, enter the interval in address 2776. The unit is in seconds. If the value is 0, the
compressor will run only once after the one-shot pump run. The operating time of the compressor is
written in address 2777. This unit is also in seconds.
Washing-pump: When the output is set to washing pump function, the output will go high when pump 1 or
2 is running and the level is decreasing.
The washing pump has its own start/stop levels which are located at the following addresses:
Initial level of washing pump is approx. 2785, the unit is the same as for level measurement on AI1.
Stop level for flush pump is approx. 2786, the unit is the same as for level measurement on AI1.
The washing pump function is only activated when the level has been above the starting level and then falls
below the starting level. If the level rises to more than 10% of the start level of the washing pump, it stops
again and awaits a level below the start level
Dosage-pump: When pump 1 or pump 2 is running, the output will pulse, the time between each pulse is
set in the parameter "Delay before ON in seconds" and the ON time of the pulse is set in the parameter
"on-time by time control in seconds".
Aumagear: This function is yet to be implemented
Bassin-PST: This feature requires that a VI6 level sensor is fitted to the SPIDER. The level sensor has its own
start/stop levels set in addresses 2785 and 2786. If the level in the pump sump detects a high limit of the
level, the basin pump will stop. When the high limit in the pump sump disappears, a pause of xx seconds is
held. This value is located at address 2776.
NOTE: The start/stop registers for basin control are also used as levels for the washing-pump function, so
be aware when using basin control and washing-pump on the same SPIDER controller.
