Voltmeters and Ammeters are also used in an economical manner by measuring single-phase with relay options.
Functions used are as follows:
LO: Lower Limit Value: The set value given by the device LO relay by accepting the value low. Relay output function starts to work when This value is lower than the value read.
HI: Upper limit values: The set value given to the HI relayby accepting a high value . If the value read is equal or bigger than this value the output function starts to work by itself.
ST: Relay operating delay: It determines when the relay function is activated according to power reaching time to the device (Waiting time)
dT: Decision delay: Time values are entered here if a status appears which requires a function to work.
PL: The time for the towed relay: If Relay desired to be towed for a short time during each reading , a non-zero value is entered here. This value is the time required for the relay remains towed in milliseconds
Zr: Zero-value function: In general, the current is zero when the system is not running. LO function is not required to work. However, in the systems that can be considered as an error, you may need to see zero amps such as low flow . In this case, if the zero is made 1, ampere value of 0 is processed by accepting it as the low current value.
Hr: The sealing function : If the user wanted it to remain towed even the relay current turns to normal and when the relay output is given, this function is entered as a value of 1.
Thus, the relay remains towed until the energy goes or you press moved up and down arrow buttons.
Sr: Limit adjustment function; This function allows you to make settings by comparing the highest value and HI value using measured values in a certain period of time.
If the highest value you read is lower than the LO, LO relay, if it is bigger than HI value, HI relay is energized.
It can be used Inrush current strokes. For example, welding machine current, such as on-off tests.
HZ: Reading speed function: It is a reading speed setting function various the reading speed of the base can be increased or reduced according to the various applications.
Thus, slow or reflex operation of the device can be achieved.
The value entered here, shows how many reads the device does within 10 seconds.If 1 is entered, the display rate is 1 in 10 seconds.
Default value is 1, but can be increased up to 50. So, reading speed can be increased. up to 5 seconds.
Effect on other functions: If PL adjustment to be made a non-zero value, should not be entered in the accelerated system. For example, the relay operates continuously towed in a system that makes 5 readings per second, if it is entered close or higher than 200 milliseconds.
