Operating Manual PMD s10
22092-EN-05 | 11
5 Function description
The PMD s10 monitors the set upper and lower true power limit on a single or three phase
supply or on the DC supply. The unit operates in accordance with the principle of Aron cir-
cuit.
}Relay outputs (K1 and K2):
K1 and K2 operate in normally energised mode. In their default state, auxiliary contacts
11-14 and 21-24 are closed and auxiliary contacts 11-12 and 21-22 are open. Normally
energised mode is the default setting. This setting can be changed via the menu.
}Analogue outputs (Uout and Iout):
The unit forms two output signals which are proportional to the true power. The final
value /limit value/ end value corresponds to Pmax (see function diagram). The status of
the threshold monitoring function is displayed at the auxiliary contacts and LEDs, along
with the analogue output signals. The hysteresis of the switching thresholds can be set
between 0 % ... 50 %.
}Current transformer CT:
With continuous currents > 12 A the measuring current must be measured via an external
current transformer.
}Voltage transformer VT:
With constant voltage > 500 V the voltage has to be measured via an external voltage
transformer.
}Po function (K1 overload):
If the measured true power exceeds the switching threshold Po, the LED "> max" is lit.
Once the reaction time has elapsed (tr), the auxiliary contact switches (default: relay K1)
and the "Out 1" LED is lit.
}Pwo function (overload warning threshold):
Serves as a warning. See Po function (K1 overload).
}Po function (K2 underload):
If the measured true power exceeds the switching threshold Po, the LED "> min" is lit.
Once the reaction time has elapsed (tr), the auxiliary contact switches (default: relay K2)
and the "Out 2" LED is lit.
}Pwu function (underload warning threshold):
Serves as a warning. See Pu function (K2 underload).
}Start-up suppression time (tstart):
The measurement is suppressed during the machine's start-up phase, in order to avoid
spurious output signals. The start-up suppression time tstart is infinitely variable.
}Reaction time (tr):
In the case of transient load fluctuations, the switching threshold can be suppressed. The
reaction time tr is infinitely variable.
}Reset mode (Reset):
The fault status (value below Pu or above Po) can be reset automatically or via an ex-
ternal reset button.

INFORMATION
Measuring range limit value Pmax (selectable)
When simultaneously using an external current and an external voltage
transformer, the selectable measuring range limit value is calculated from
the following formula:
Pmax = (1.0 W … 11.5 kW) x CT x VT
Examples:
1. Current transformer CT 100 : 1 and no voltage transformer VT 1 : 1
Pmax = (1.0 W … 11.5 kW) x 100 x 1 = 100 W … 1.5 MW
2. Current transformer CT 1000 : 1 and voltage transformer VT 100 : 1
Pmax = (1.0 W … 11.5 kW) x 1000 x 100 = 100 kW … 1.5 GW

Installation
