SETUP
READ THESE INSTRUCTIONS BEFORE YOU BEGIN INSTALLATION.
Ground yourself before touching any electronic equipment. Some components are static sensitive.
Mounting:
The interface device may be mounted in any position. If circuit board slides out of snap track, a non-conductive “stop”
may be required. Use only fingers to remove board from snap track. Slide out of snap track or push against side of snap
track and lift that side of the circuit board to remove. Do not flex board or use tools.
POWER CONNECTIONS – THIS PRODUCT ACCEPTS 24 VDC OR 24 VAC POWER.
NOTE
#1
Be sure to follow all local electrical codes. Refer to wiring diagram for connection information. Make all
connections with the power off.
1.) The secondary supply voltage to the interface should be between 22 and 28 volts AC or DC and
isolated from earth ground, chassis ground, and neutral leg of the primary winding. If required by
BAS or controller specification, the 24 VAC neutral can be earth grounded at the transformer.
Analog input, digital input, and analog output circuits should not be earth grounded
at two points. Any field device connected to this transformer must use the same common.
If you are not sure of other field device configuration, use separate transformers for isolation.
2.) If the 24 volt AC or DC power is shared with other devices that have coils such as relays,
solenoids, or other inductors, each coil must have an MOV (if AC), a diode (if DC), AC or DC
transorb, or other spike snubbing device across each of the shared coils. Without these
snubbers, coils produce very large voltage spikes when de-energizing that can cause
malfunction or destruction of electronic circuits.
3.) You should measure the actual voltage output of the secondary. If the output is not fully loaded
you may read a higher voltage than the circuit board can handle.

SIGNAL CONNECTIONS
With power off, connect analog input signal common (-) to terminal Com and analog input signal positive (+) to terminal
Sig.
Terminal C is ATP signal output common.
Terminal NC is normally closed (connect signal output here if you want reverse acting output)
Terminal NO is normally open (connect signal output here if you want direct acting output)
APPLICATION DETAILS
Program # 01000300 converts an analog signal into a digital pulse output signal of 1-11 seconds.
Program # 0208Y0A converts an analog signal into a digital pulse output signal of 0-21 seconds.
Check the chip label on your ATP to verify you have the correct program version.
Both are designed to convert an analog signal to a pulse signal to control a York Codepak™ Chiller Control Center.
A maximum of one reset pulse is allowed in a 60 second window.
If Voltages higher than 24 VDC @ 2 Amps are switched on the chiller control package, a relay should be installed, with
the ATP acting as a pilot relay.
ANALOG INPUT JUMPER SETTINGS
The analog input signal range is selectable by jumper shunts P2 and P3 (see chart on page 1).
ATP PULSE TIMING OUTPUT SETTING FOR BOTH YORK CHILLER PROGRAMS
All DIP switches should be in the OFF position.
OPERATION
Apply power.
VERSION 010003000 – York 1 to 11 Second Pulse
Transmitter pulse ON time will be between 1 to 11 seconds. The ON time is proportional to a 0 to 100% input range.
The total cycle time is 60 seconds.
LED flashing one second on and one second off. No analog signal detected or signal is less than 0.07 VDC.
LED on solid: ATP is now transmitting output pulse.
LED quickly flashes: Output pulse has occurred and is now continuing the remainder of the 60 second cycle time.
VERSION 0208Y0A – York 0 to 21 Second Pulse
LED has no function
Transmitter pulse on time will be between 0 to 21 seconds. The ON time is proportional to a 0 to 100% input range.
The total cycle time is 60 seconds.
