Description:
ThisdeviceisusedtodisplayandmonitorDCvoltage.Maximum&Minimumvaluesareloggedfor24hours(updatedevery60min).
The relay(s) may be used for over and / or under protection. The latch facility may be de-activated for one or both the relays
allowing one relay to be used for control (not latched), and the other as a latched alarm. Use the “ScAL” parameter for calibratio
n
purposes, or to change the number of decimal places displayed (see notes). Other features include adjust able signal damping,
adjustable start-up and reaction delays, the ability to swap the relay’s functionality.All settings may be locked & code protected
toavoidchanges from being made byunauthorisedpersonnel.
0RELAY
This device is used to display DC voltage.
1RELAY
Thevoltageappliedisdisplayedaccordingtothescalespecified.The relay remains energised while the input signal is betwee
n
the upper and lower set points. Once de-energised, the signal must change in the opposite direction by the hysteresis amou
nt
before the relay will re-energise. The relay’s action may be swapped to energise when the setpoint is reached. Note: the relay
will NOT re-energise while the latch pins are shorted. The latch pins can also be used as a reset.
2RELAY
The voltage applied is displayed according to the scale specified. The relays remain energised while the input signal is betwee
n
the upper and lower set points. Once de-energised, the signal must change in the opposite direction by the hysteresis amou
nt
before the relay will re-energise. Either relay’s action may be swapped to energise when the setpoint is reached. Note: the
relay will NOT re-energise while the latch pins are shorted. The latch pins can also be used as a reset.
Adjustable parameters:
P
lease note: Depending on the model of the device purchased, some of the parameters listed below may not be available
·Upper limit for relay 1 “Hi 1” (default: disabled)
When the input rises above this value, the relay changes state until the signal drops by the hysteresis amount
(see“HYS.1”setting)
·Lower limit for relay 1 “Lo 1” (default: disabled)
When the input drops below this value, the relay changes state until the signal rises by the hysteresis amount
(see“HYS.1”setting)

·Hysteresis value for relay 1 “HYS.1 “ (default: 0.5 )
Oncetheset-pointisreached, (&relay changedstate),theinputsignal mustchange (intheoppositedirection)by thisvalue beforetherela

a
fault condition exists, but the relay is being held energised by the start-up or reaction delay timers, “-r1-” or “-r2-” is displayed.
Changingthis setting to “off”,disables these messages. Note:Thissettingdoes not affectthe “Er.Hi” and “Er.LO” messages. (see
notes)

commissioning.(usetheadvancedmenu)
· The maximum & minimum values are NOT updated during the first 30 seconds after power up. This allows the input signal to
stabilize first.

To clear the code, re-enter the same code again.
If the code is forgotten. Press and hold “+” & “-” (“S”and “T” ) until “CODE” is displayed while re-applying power to the device.
re-transmit Notes:
· The output 4-20mAis dependant on the value being displayed, and is set up in a similar manner to the display.The offset
parameter determines when 4mA is output, and the span is the amount required for the output to increase by an additional
12mAie. 20mAis output when the value displayed = re-transmit OFFSET+SPAN
· To set the re-transmittion signal to follow the input signal (the output 4-20mAfollows the 4-20mAreceived), set the re-tx offset
and span settings to the same value as the display offset and span settings.
· To set the re-transmittion signal to invert the input signal (the output = 4mAwhen the input = 20mA), set the re-tx offset = (display
offset+span)andre-txspan = (display span x -1).
· Whenever the input signal is above or below the “CAL.O” or “CAL.S” values by more than 3%.The display indicates “Er.Hi” or
“ER.Lo”.
· Certain settings are reset to default when the device is re-configured. Re-check all settings to ensure they are correct before
commissioning.(usethe advanced menu)
