MEASUREMENT RANGES
EPM-4D (Ammeter with Demand) : EPM-4D is designed to measure RMS value of AC current which flows
from the line and saving the instant and average demands. The current transformer ratio can be set between 5/5A
and 10000/5A by the buttons on the panel.
(drCt is not
available for
EPM-4D.)
(drCt valid when
CT-25 is used)
1
EPM-4C (Ammeter with Setpoint) : EPM-4C measures the RMS value of AC current which flows from the
line. If the measured AC current is over the high setpoint or it is under the low setpoint, output relay is switched
on at the end of adjusted time delay. Also, it includes all functions of EPM-4A.
EPM-4P (Ammeter with Pick-Up) : In addition to EPM-4C, it also has Pick-Up relay. If the measured AC
current is over the high setpoint or it is under the low setpoint, Pick-Up relay is switched on without delay. If current
value returns within preset limits before the end of programmed delay time, Pick-Up relay is switched off without
delay.
* Important Notice: The secondary value of current transformer must be limited at 5A.
Turn ( ) : Turn number of cable, which passes inside of CT-25 is selected in this menu. This number can
be selected between 1 and 10. If only drCt is selected under Ctr menu, turn number will be activated.
Demand Time ( ) : Device records measured demand and maximum demand values. Demand is the
average current value measured in demand time. Maximum demand is the maximum average current value
measured in demand time. Maximum demand value remains stored, even if the power supply is off and demand
value becomes 0 (zero).
Setpoint (s p s p v e ): When the AC current which flows through the device is over the high setpoint
value or it is under the low setpoint value, the output relay is switched on in order to generate an error signal at
the end of programmed delay time. If the AC current value returns within preset limits, before the end of the delay
time, the relay resets itself and no tripping occurs.
Latch Function ( ) : Latch function is used to select the output relay operation mode. Either oF
or on position may be selected.
At position oF: If the current value returns to preset limits, output relay is switched off.
At position on: Even if the current value returns to preset limits, output relay remains switched on and
switches off only by pressing the Set button.
Instant Tripping ( ) : If the AC current value is over the1,5 times of setting value or it is under the 0,5
times of setting value, the output relay is switched on without any delay time. This function is user-selectable.
Start Time Delay ( ): When the current starts to flow initially, the setpoint values are ignored for the
determined time. If auto start mode is activated, after the AC current is cutted, the device returns into its initial
state.
Automatic Start Mode ( ): If this function is disabled (off), start-up delay (Strt) is activated only when
initial current is applied to the measurement input of device. However, when this function is enabled (on), if
measured current value decreases to 0 (zero) value and increases again, start-up delay is activated.
Note : If the current on the measurement input of the device is over 6 A or measurement according to entered
primary value of current transformer is over 9999 A, there will be hý on the display.
Example: If a current transformer which has a ratio of 80/5 A is used,
current transformer primary value is entered as 80.
