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)

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.

* Please check the device label for proper value.

* Different supply voltages are adjustable upon request.

Precautions For Installation and Safe Use

Failure to follow below instructions will result in death or serious injury.

Disconnect all power before working on equipment.

When the device is connected to the network, do not remove the front panel.

Do not try to clean the device with solvent or the like. Only clean the device with a

dried cloth.

Verify correct terminal connections when wiring.

Electrical equipment should be serviced only by your compedent seller. No responsibility

is assured by the manufacturer or any of its subsidiaries for any consequences arising

out of the use of this material.

Only for rack panel mounting.

Warning :

a) A switch or circuit breaker must be connected between the network and the auxiliary

supply input of device.

b) Connected switch or circuit breaker must be in close proximity to the device.

c) Connected switch or circuit breaker must be marked as the disconnecting device

for the equipment.

d) The type of the used fuse must be FF type and the current of the used fuse must be 1A.

e) No need of a vantilator in the installation area

f) Practical user manuel must be put on the panel.
