Installation – hardware

VS102 has two different mounting plates and two different mounting studs. See figuration below. Be

aware of that VS102 will sense the vibration in the vertical axis reference to the mounting plate.

Note: 1.Select Relay/Triac NO/Triac NC as per Alarm option

2. If single alarm is selected, Alert is valid only

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.

COM: System ground

BUF: Buffered output

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

NC1: Alarm 1. Normally closed

ARM1: Alarm 1. Arm

NO1: Alarm1. Normally open

NC2: Alarm2. Normally closed

ARM2: Alarm 2. Arm

NO2: Alarm 2. Normally open

+24V: Power input (DC)

POW+/POW-:Power input(AC) Caution:

J101 for high voltage power supply and J107 for low voltage. Wrong setting will destroy the

switch!

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.

9Power on

9Connect a ampere meter to the 4-20mA terminal

9Zero adjust: hold down RESET/SETET button for 10s, OK LED and Alert LED flash and the

instrument changes into 4mA calibration mode. Pressing + or – button to make the instrument

output a current of 4mA. Press RESET/SET button again, ALERT LED flash. Three seconds

later, press RESET/SET button again and DANGER LED flash. Three seconds later, press

RESET/SET button again and OK LED, ALERT LED and DANGER LED flash. At last, press

RESET/SET button to withdraw from zero calibration mode.

9Adjust Alert: hold down RESET/SET button for 10s, OK LED and Alert LED flash. Press

RESET/SET button again, ALERT LED flash and it changes into Alert calibration mode. Three

seconds later, the ampere meter displays the last set alert set-point (default factory setting is

50% of full scale). Press + or – to adjust it to the desired value. Press RESET/SET button again,

DANGER LED flash. Three seconds later, press RESET/SET button and OK LED, ALERT LED

and DANGER LED flash. At last, press RESET/SET button to withdraw from Alert calibration

mode.

9Adjust Danger: hold down RESET/SET button for 10s, OK LED and Alert flash. Press

RESET/SET button again, ALERT LED flash. Three seconds later, press RESET/SET button

and DANGER LED flash and the instrument changes into Danger calibration mode. Three

seconds later, the ampere meter displays the last set DAGER set point (default factory setting is

75% of full scale). Press + or – to adjust it to desired value. Press RESET/SET button again OK

LED, ALERT LED and DANGER LED flash. At last, press RESET/SET button to withdraw from

Danger calibration mode.
