PM1000 Series Power Meters PLSED309039EN

Chapter 2 – Quick Start Guide 08/2010

1. Connect auxiliary supply (control Power) 44 – 277 VAC/DC to terminals 12

and 13 in order to power ON the power meter.

 Keep pressed for two seconds, while powering up the power meter.

The power meter directly enters into PROG menu setup and displays

EDIT A.PRI 100.0.

Program the following setup parameters for accurate readings:

 A.pri, A.sec: Set these values to match your CT primary and

secondary values. For example, if your CT Ratio is 200:5, set A.pri =

200.0 and A.sec = 5.000.

 V.pri, V.sec

 Set these values to match the input voltage VLL of circuit, if the

input voltage < 480 VAC LL. For example, if input voltage = 300

VAC LL, set V.pri = 300.0 and V.sec = 300.0.

 Use potential transformer (PT/VT), if the input voltage > 480 VAC

LL. Set the V.pri and V.sec values to match the primary and

secondary of the PT(VT) respectively. For example, if PT(VT) ratio

is 11 kV: 110, set V.pri = 11.00 k and V.sec = 110.0.

Select one of the following systems according to your wiring

configuration:

 SYS: DLTA for 3-phase 3-wire system

 SYS: WYE/Star for 3-phase 4-wire system

 SYS: 2-phase for 2-phase 3-wire system

 SYS: single-phase for single-phase 2-wire system

2. Connect the current transformers (CTs).

3. Connect the voltage inputs. Use PT(VT), if voltage exceeds 480 VAC LL.

4. RS 485 terminals (PM1200)
