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.
