Testomat EVO TH CAL - Limit Value Monitoring; Input Operating Mode of LV1 and LV2 Limit Value Outputs; Select Measurement Value Unit

Input basic programming data
36
Select measurement value unit
You can program the unit of the value shown. Your selection options
include °dH, °f, ppm CaCO
3
as well as mmol/l. All the following inputs
and indications will then be shown in the programmed unit.
 Select in the menu =>Basic program=> display of
unit
 Select the desired unit
(The factory default setting is the °dH unit)
 Confirm the selection with "OK"
Limit value monitoring
You can program the limit values to be stepless. The limit value
range is specified by the indicator type and programmed unit used.
You can monitor two limit values. For this purpose, each limit value
output is available. The functions of the assigned delay outputs can
be programmed independently of each other.
The limit value outputs are permanently assigned to limit values!
(GW1/2 are available on the LV1/2 terminals.)
LV1 = limit value 1 LV2 = limit value 2
If the limit value LV1 is exceeded, the limit value control indicator
lights up in RED and the relay output LV1 responds according to
the programmed switching function. If the limit value has not been
exceeded, the indicator lights up in GREEN. The same functional
approach applies to the limit value LV2.
Entering the limit values
 Select in the menu => Basic program => limit values
 Input the values for "LV 1" or "LV 2"
 Confirm the input with "OK"
Input operating mode of LV1 and LV2 limit value
outputs
 Activate the operating mode for both relays via
=> Basic program => Function LV1/LV2
The following operating modes can be configured:
Limit value operating mode
A limit value may be defined for both relays. The relay switches when
the limit value is exceeded.
