4. COMMISSIONING

When HMP230 transmitters leave the factory, their measurement ranges and

output signals have already been scaled according to the order form completed

by the customer. Units are calibrated at the factory and ready to operate when

the power is turned on. If you take into use active current, voltage or serial bus

outputs, make these connections first; Appendix 9 describes them in detail.

NOTE

Make sure that the power is not turned on until cables

have been connected to screw terminals!

In transmitters with display, the software version appears for a few seconds

when the power is turned on. After this, measurement results appear

automatically. Should an error message appear on the display, consult

Appendix 5.

If your transmitter has a blank cover and the LED indicator inside the housing

lights up, consult Appendix 5 for further information.

Appendix 7 contains information on how to determine the ranges for alarm

outputs and alarm controls when an alarm output unit is used.

4.1. Changing the parameters

If necessary, the user can subsequently change the measurement units between

metric and non-metric and select and scale the output signals with software

functions. This is done through commands, either utilizing the menus on the

local display or giving commands through the serial interface (see

Appendices). Most often the commands are used to change the settings of the

two analogue channels.

4.2. Security lock jumper

Before the settings can be changed, the user must first remove the security

lock jumper in connector X15 (see Figure 22). The security lock jumper makes

it impossible to change the transmitter settings by mistake.
