HotSpot-Z — Temperature Alarm

SmartFan HotSpot-Z is a compact, multiple-

output temperature alarm. Trigger tempera-

ture is adjustable by means of a jumper on

the circuit board. Normally open or normally

closed outputs can drive a logic circuit, LED or

piezo alarm. Alarms are referenced to ground.

An additional normally closed optically isolated

output is provided. HotSpot-Z is compatible

with temperature sensors P1 through P9 shown

on page 34.

•Wide input voltage range of 5.0 to 25.0 VDC

•Selectable alarm trigger temperature of 45°, 50°, or

55°C (86°, 92° or 98°C when P3 sensor is used)

•Normally open and normally closed outputs provide

nominal 8 mA to an LED connected between the

output and L. They can sink at least 4 mA at 0.4 VDC

to drive a logic circuit. A piezo alarm would be

connected between NO and +. Outputs are

referenced to ground

•Optically isolated output sinks at least 1 mA at 0.4 volts

•Optional isolated MOS relay alarm output for high

current or high voltage applications

Normally Closed (E,C) Alarm Output: Optically

isolated to drive logic circuits. Closed and can

sink at least 1.0 mA at 0.4 volts below trigger

temperature. Open above trigger temperature

and will accept up to 30 VDC.

Normally Closed (NC) Alarm Output: Closed

below trigger temperature and will sink 4 mA at

0.4 volts or less. Open above trigger temperature

and will accept up to 30 VDC. Applies nominal 8

mA to an LED connected from NC to L.

Normally Open (NO) Alarm Output: Open below

trigger temperature and will accept up to 30

VDC. Closed above trigger temperature and will

sink 4 mA at 0.4 volts or less. Applies nominal 8

mA to an LED connected from NO to L. Applies

nominal power supply voltage to a piezo alarm

connected from NO to +.

HotSpot-Z — Installation & Operation

INSTALLATION

Power-In Connections (J3)

Connect the power supply between pins - and +

on header J3 using any voltage between 5 and

25 VDC. Power supply current is 10 mA maximum

at 12 VDC plus an additional 8 mA for an LED

if used.

Sensor Connection (J2)

Sensors are shown on page 34. There is no polarity

consideration when connecting the sensor.

OPERATION

Setting

Trigger Temperature (J1): Use this jumper to

set the trigger temperature to 45°, 50°, or 55°C.

Factory setting is 50°C. If the P3 sensor is used,

trigger temperature settings are 86°, 92°, and

98°C.

Alarm Outputs (J3)

Normally Closed, Isolated Output: This output

is intended for connection to a logic circuit. An

optically isolated NPN transistor is connected to

pins J3:E (emitter) and J3:C (collector). The out-

put is closed and can sink at least 1.0 mA at 0.4

VDC for temperatures below the trigger temper-

ature. Above the trigger temperature, the tran-

sistor is open and up to 30 VDC can be applied.

Non-isolated Outputs: The NO and NC outputs

can be used to provide a logic gate or LED alarm

indication.

For logic circuit alarm indication, each alarm

output can sink up to 4 mA at <= 0.4 VDC. When

open, a maximum of 30 VDC can be applied to

each output. Power for an LED alarm indication

is provided by Pin J3:L via an internal 12 mA DC

constant current source. An LED connected

between NO (normally open) and L will light

above trigger temperature. An LED connected

between NC (normally closed) and L will light

below trigger temperature. A piezo alarm would

normally be connected between NO and +.

Above trigger temperature, the supply voltage

is applied to the piezo alarm.

Note: L is positive (+); NC and NO are negative (-).
