Function
The voltage measuring relay SUM 1001 is a monitoring relay for singlephase voltages. The measurand is supplied via various terminals, based
on the desired operating range (see Table I). With the potentiometer
target value, the response value can be set analogously within the preselected operating range. The operate time delay can be set with the time
domain switch and the potentiometer time target value (see Table II).
Notes:
• The supply voltage is galvanically separated from the measurement
circuit and is displayed via the LED "SUPPLY".
• The measurand is recorded with an integrating full-wave rectification.
With that, in certain limits, the monitoring of voltages, which are not sineshaped (e.g. voltages with a harmonic wave concentration, square or
triangular voltages in the range of 45 - 400 Hz) is possible.
• The devices assess (for AC) the rectification value calibrated to the
effective value of a sine voltage.
• For DC measurands, a rectification occurs and the mean value is monitored.
• In the delay domain NO DELAY and with the simultaneously poweredon function measurand exceedance (> V) the monitoring relays respond as of a certain threshold to the present value of the measured
variable, and the output relay toggles instantaneously (see technical
data).
• Prior to the insulation or voltage test in the switching installation, the
connector lines are to be disconnected from the voltage measuring
relay.

Function operating current principle
After application of the supply voltage and the falling below or exceeding of the preselected response value (based on the function selection see Table III), the output relay toggles to the operating position. This
takes place either after the preselected response delay or immediately. If
the response value - based on the setting - falls below or exceeds by at
least 3 or 10 % (hysteresis), then the output relay returns to the Standby
position.
Function standby current principle
After application of the supply voltage, the relay toggles to tB, to the
operating position. If the preselected limit value falls below or exceeds
(based on the function selection), then the output relay re-toggles to the
Standby position, depending on the preselected delay time. According
to the preselected hysteresis (3 or 10 %), the output relay re-toggles to
the operating position after falling below or exceeding the response
value.

If the measurand exceeds the target value of 25 V, then the LED TRIPPED
starts flashing. After the elapse of the preselected operate time delay of
210 s, the output relay toggles to the operating position, and die LED
TRIPPED stays on. If the actual value of the measured variable falls below
the target value minus the 3% hysteresis, then the output relay retoggles to its Standby position. If the measurand falls below before
reaching the preselected time, then the LED "TRIPPED" goes out (see
function diagram 1).
If the measurand falls below the target value of 4 V, then the output relay
without time delay toggles to the Standby position, and the LED
"TRIPPED" lights up. If the actual value of the measured variable exceeds
the target value plus the 10% hysteresis, then the output relay toggles to
the operating position. The LED "TRIPPED" goes out (see function diagram 4).
