== Relay panel technical information ==
The control panel, sometimes referred to as a master clock, head unit, and may be an electronic carillon is usually located in a sacristy or office area. Many times to save long wiring runs, it may be installed in a balcony area near the tower. In all cases, no ladders should need to be used to access the control panel.
=== Lights and test buttons ===
At the top of the relay panel is a square board with three buttons with four lights at the top edge.


The four lights are labeled:
==== Relay panels ====
Power - Data - Fault - Status
High current switching should be as near the bells as practical. The weather resistant relay panels are, in most cases, installed in an enclosed tower chamber below the bells. Precision intelliSwing motor control panels should be within sight of swinging bells for ease of programming.
The buttons may be labeled:
Reset - Test - Step


At the bottom of this board, and sometimes installed on an auxiliary board attached with a ribbon cable, are one inch square output modules mounted vertically (four outputs on the main board, twelve outputs on the auxiliary board). For tolling outputs, there will be two timer adjustment controls. For motorized ringers there will not be adjustments. At the top of these boards is a green light that indicates the output is on. At the bottom of the board is a red light that indicates the output is driving a short circuit.
To prevent moisture from accumulating in the panels, always route conduit to the bottom of the boxes. '''NEVER''' penetrate the top surface of a relay panel.

Hold the Test button (under the Data light) while momentarily clicking the Reset button (under the Power light). After the Fault light blinks you can let go of the Test button. The Data light should remain lit to indicate the panel is in the self-test mode.

Press the Step button to sequence through the outputs. The tolling outputs will ring first then any motorized outputs will follow. Note that after ringing the Motorized outputs, the toll outputs will may locked out (hammer protect mode). If you need to test the tollers again, repeat the procedure above to reset the test mode (after the bells have ceased to swing).
==== Mechanical actuators ====
Tolling hammers, clappers and swinging motors are installed on the bells themselves and are usually supplied with at least an 18 inch pigtail. Junction boxes need to be located near enough to the actuator to allow connections. Flexible conduit is helpful to allow junction boxes to be re-located during the equipment installation. Separate low current conduits should be provided for swinging motor motion feedback signals (generally 12VDC logic signals).


To repeat an output that you have stepped to, press the Test button to repeat it. This is useful for testing motorized outputs that time out after a second or so.
Bells are always numbered from the largest (bell 1) to the smallest.


==== Exit test mode ====
For swinging bells, the wheel side of the bell is where the swinging motor will be installed, and a tolling hammer will always be located on the opposite side from the wheel.
The panel will reset to the standby mode in a couple of minutes. For immediate reset, press the Reset button so that the Data light goes out.


=== Pulse Adjustments ===
Stationary bells can have either outside tolling hammers or inside clappers. The electro-mechanical and physics aspects of this choice generally is made on the basis of how loud the bell is intended to ring. Gravity favors outside hammers helping the power of the striking of the bell. Gravity works against inside clappers resulting in a softer tone. Visual esthetics aside, choose clappers for musical instruments and hammers for tolling bells.


Each timer board has two adjustment potentiometers. The top adjustment sets the length of the pulse and the bottom adjustment sets the maximum repeat rate. For both cases, clockwise adjustments shorten the pulse and allows smaller bells to repeat faster.
If the lower potentiometer is adjusted counter clockwise more than the upper adjustment, the ON pulse will be shortened to allow faster repeats.
==== Pulse setting procedure for large tolling bells ====
#Set the top adjustment fully clockwise
#Set the bottom adjustment fully counter-clockwise
#Turn top adjustment counterclockwise until the ringing does not get any louder
==== Pulse setting procedure for small chime/carillon bells ====
#Set both adjustments fully clockwise (short pulse)
#Turn top adjustment counterclockwise until the ringing does not get any louder
#If the top adjustment is fully counterclockwise and you can get the bell to ring louder by turning the bottom adjustment farther then continue adjusting the bottom adjustment until the desired performance is obtained.
== Troubleshooting ==
=== Fuse blows ===
==== Test Open Output ====
Disconnect output wires from PCB for the bell that blows fuse. If fuse still blows without anything connected, the rectifier is probably at fault. Most panels have socketed rectifiers that can be replaced. Be sure to align the angled corner (positive lead) correctly when inserting the replacement.
==== Test Alternate Output ====
If the output in question does not blow the fuse when its output is not connected, try connecting the bell to another output (lower numbered output for high current fuse). If the other output fuse blows there is a problem with the striker or wiring.

Equipment and locations

Generally we provide three types of equipment to install in different areas of the facility.

User controls

The control panel, sometimes referred to as a master clock, head unit, and may be an electronic carillon is usually located in a sacristy or office area. Many times to save long wiring runs, it may be installed in a balcony area near the tower. In all cases, no ladders should need to be used to access the control panel.

Relay panels

High current switching should be as near the bells as practical. The weather resistant relay panels are, in most cases, installed in an enclosed tower chamber below the bells. Precision intelliSwing motor control panels should be within sight of swinging bells for ease of programming.

To prevent moisture from accumulating in the panels, always route conduit to the bottom of the boxes. NEVER penetrate the top surface of a relay panel.

Mechanical actuators

Tolling hammers, clappers and swinging motors are installed on the bells themselves and are usually supplied with at least an 18 inch pigtail. Junction boxes need to be located near enough to the actuator to allow connections. Flexible conduit is helpful to allow junction boxes to be re-located during the equipment installation. Separate low current conduits should be provided for swinging motor motion feedback signals (generally 12VDC logic signals).

Bells are always numbered from the largest (bell 1) to the smallest.

For swinging bells, the wheel side of the bell is where the swinging motor will be installed, and a tolling hammer will always be located on the opposite side from the wheel.

Stationary bells can have either outside tolling hammers or inside clappers. The electro-mechanical and physics aspects of this choice generally is made on the basis of how loud the bell is intended to ring. Gravity favors outside hammers helping the power of the striking of the bell. Gravity works against inside clappers resulting in a softer tone. Visual esthetics aside, choose clappers for musical instruments and hammers for tolling bells.
