Hydroranger 200: programme the second 4-20ma output to the same value as the first

Hi, i wonder if anyone can give advice, i have a Hydro ranger 200 six relay model, it will accept two ultra sonic heads and has two 4-20ma outputs.

The installation i am working on has one u/s head installed and one 4-20 output used.

i would like to programme the second 4-20ma output to the same value as the first, ive been through the manual and im struggling to find the correct menu to enable and assign the output.

Any help would be appreciated.

Thanks

Hi Red2door,

apologies for the delay in getting back to you. You have not stated whether your unit is an HMI version or not. Dan has kindly provided you information regarding the HMI version, you may have a "classic" version, though. I will answer for both.

In order to get the second mA working with the first/only transducer you need to set up mA output 2. This is achieved by using the index "function". Every parameter that has more than one option - for example the relay outputs (indexed 1 to 6), or the transducer inputs (indexed 1 and 2) - have an array of options under them. So, taking the "classic" version (programming via hand held programmer) you would need to ensure that the following parameters are properly set:

P200 index 1 - set to the mA range for output 1, normally 2 for 4-20mA

P200 index 2 - set to the mA range for output 2, normally 2 for 4-20mA

P201 index 1 - set to the mA function for output 1, 1 for level, 2 for space etc.

P201 index 2 - set to the mA function for output 2, 1 for level, 2 for space etc.

P202 index 1 - set to the point you wish to be output for mA 1, 1 for transducer 1, 2 for transducer 2, 3 for calculated (normally differential), 1:2 for average of txders 1 & 2.

P202 index 2 - set to the point you wish to be output for mA 2, 1 for transducer 1, 2 for transducer 2, 3 for calculated (normally differential), 1:2 for average

So, assuming you want both outputs set for txder 1 level at a 4-20mA scaling your parameters should look like: P200:1 - 2, P200:2 - 2, P201:1 - 1, P201:2 - 1, P202:1 - 1; P202:2 - 1. This would set both mA outputs to react to the level read on transducer 1 over the range 4-20mA.

On an HMI version (with push buttons under the display and plain text parameters) this would be accomplished as follows:

mA output selector (2.5.1) - mA 1 <- this has to be set to make sure the index on the following parameters corresponds to the output you want to set up

mA output range (2.5.2) - 4 ... 20mA

Current output function (2.5.3) - Level

mA output allocation (2.5.4) - Point 1

then you go back to mA output selector and select mA 2 and then repeat the above settings for 2.5.2, 2.5.3 and 2.5.4.

Now both of your mA outputs will provide exactly the same signal.

Hi, thank you for that explanation, and yes its the classic model. The second functions was the part i was struggling with so your break down will help me greatly.

Ill dig out the programmer and go for a second round with it.

Thanks R2D
