Function description:
RST/BYP: Alarms reset / Bypass(When short circuit with COM, OK/TX/BYPASS LED turns red,
alarm status draws back). There are two types of bypass, hardware bypass and
software bypass. When hardware or software bypass is active, the Bypass LED
comes on. Both types of bypass do not take effect on monitoring except the alarm.
They are valid for both Alert alarm and GAP alarm. The default status is inactive.
Bypass has a higher privilege than alarm latch does.

BUF: Buffered output
4-20mA: Transmitting of overall to up-level PLC/ DCS/monitor/computer

VS102 Operation
VS102 display and status
VS102 will have status indication:
9BUF: Buffered output.
9OK: green/red LED. Normally green. With not OK or no power supply, the LED is off. In bypass
mode, the LED is red.
9ALERT: yellow LED
9DANGER: red LED
VS102 field controls
9Reset: There are two ways to perform reset: 1. by pressing RESET/SET button; 2. by pressing
Local button; there is a lever on the instrument cover, whose being pressed will cause the alarm
reset. Note: It works only when the measured variable is less than the alarm set-point.
9Remote reset / Bypass: Brief short the RST/BYP pin to COM will reset the system. Continue
short the RST/BYP pin to COM will disable the alarms to realize bypass.
9Buffered output: a raw signal can be accessed by the BUF pin. There is 100 ohms output
impedance. The output can drive up to 300 meters (1000 ft) in distance between a condition
monitoring system and VS102.
9Alarms: User could select it as per category (Dual SPDT Relays Single SPDT Relay Single
SPST Triac, NO Dual SPST Triacs, NO Single SPST Triac, NC Dual SPST Triacs, NC）
9Power input: VS102 can be configured to work with either high voltage (95 to 250 VAC) or low
voltage (22 to 30 VDC).
VS102 zero and alarm set-point configuration
VS102 can be field configured with zero and alarms set-points.

Trouble shooting
1. The instrument is NOT OK after powered on
Inspect whether its power supply is correct referring to the field wiring diagram; inspect whether
the delay period expired.
2. The instrument has no 4-20mA output
Inspect whether its power supply is correct referring to the field wiring diagram; inspect whether
the cables and 4-20mA terminals are connected correctly. If the power supply is okay, LED
indicates okay, the instrument should outputs a current of within 4-20mA.
3. Hardware zero point and alarm can not be adjust
Inspect whether its power supply is correct referring to the field wiring diagram; inspect whether
the cables and 4-20mA terminals are connected correctly. According to the relevant part of the
user manual, adjust it while the corresponding LED flash. Note, when ALERT LED and
DANGER LED flash, It is needed to wait three seconds before pressing + and/or – to adjust the
set point.
4. Instrument outputs with great error
Ensure that the instrument is installed correctly and reliably. Its terminals are connected
correctly and reliably.
5. Alarm status is abnormal
Inspect whether the instrument is powered correctly referring to the field wiring diagram; the
cables and the terminals are connected tightly. Make sure that the connected instrument’s rated
power suffices the relays and triacs’ requirement (RELAY: 5A 230VAC/115VAC TRIAC: 5A
230VAC). According to the Alarm option in the category, connect terminals correctly, referring to
the field wiring diagram. If the instrument behaves normally, when the alarm set point has been
broken and retained for a time of alarm delay, corresponding LED lights up and relay and triac
activates.
6. Measurement value increases abruptly or causes false alarm when using high frequency
devices(e.g. interphone)
It is caused by the installation method of vibration switch. The ideal method that all the wires of
connecting vibration switch go through the metal conduit. Provibtech recommends to use this
method; if there is no this installation condition in the field, it needs to use magnetic ring as the
appendix shows. If it doesn’t work well, please increase the quantity of magnetic ring according to
the field condition. The installation method is as follows:

Note: if the effect is not apparent, wind the wire around the magnetic ring in acircle as the following figure
shows or install another magnetic ring adjacent to the first one as the above figures.
