| Tachometers  Portable Tachs Panel Tachs Sensors | | Portable Tachometers- Pocket-Tach Series, Phaser-Tach, Tach-4A | Q. Pocket-Tach Plus Kit: Why does the tachometer display two times the actual RPM when operated in the contact mode?
A. When the Pocket-Tach Plus Kit is operated with the contact tip assembly, the tachometer must be programmed in CT-RPM under the RATE mode. The tachometer will read two times the actual RPM if the customer installs the contact tip assembly while the tachometer is still programmed in the optical (non-contact) RPM mode. When you use a contact tip assembly, all the selections for RPM and linear rates, must be set under the RATE mode. | Q. Pocket-Tach Plus Kit: The plastic black pins/bushings that hold the contact tip assembly to the tachometers have broken.
A. Contact Monarch for a free set of Nylatch fasteners. We will mail them to you at no charge. |
| | Panel Tachometers | Q. I can put an ammeter and a bench power supply on the 4-20mA output and everything works fine, but when I connect the 4-20mA output to my PLC (or other system) it doesn't work.
A. All of the connections on the back of the tach marked "com" including pin 5 of the RS232 connector are all connected together inside the Tach. The common connection of the 4-20 mA output is not isolated therefore it must be connected to the common of your 4-20 mA loop. This is usually not a problem if the ACT has an isolated power input and no other common connections are made between the ACT and the rest of the system thus in effect isolating the common. | Q. My 0-5V output works fine when I connect only a voltmeter to the tach. But the 0-5V output doesn't go all the away up to 5V when I select full scale output from the Diagnostic menu?
A. The system is drawing too much current from the 0-5V output. The 12 bit board currently can source up to 5 mA. The 8 bit board can source up to 60 mA. | Q. How can I put the tachometer into a current loop?  Download Application Note | Q. How do I know if my ACT Tachometer is reading my sensor?
A. The ACT-1A or 1B models have an on target indicator, which is the decimal point. The decimal point must be lit when the sensor is providing an input to the tachometer. ACT-2A, 3-A and 3 models have a GATE light on the display that must remain lit when the sensor provides input. | Q. How do I program my the ACT Tachometer?
A. The simplest way to program the ACT-2A, 3A or 3 model tachometers is to follow the menu overview flowchart in the rear of the instruction manual. click here to download the Instruction Manual |

| | Sensors | Q. Where can I find reflective paint to trigger my ROS?
A. Monarch Instrument no longer carries reflective paint please contact: J.P. Nissen Company Glenside, PA Phone: 215-886-2025 Fax: 215-888-0707 | Q. How do I verify operation of a Monarch sensor?
A. For the ROS or SLS, ensure the Sensor is properly powered from the instrument. A visual light will be evident. DO NOT look directly into the light source. Move a white piece of paper back and forth in front of the sensor, breaking the beam. The green "on-target" LED should turn on and off in synch to the paper movement.Proximity Sensor – P5-11: You may pass a metal object within .20 inches from the end of the sensor and the on target indicator will blink on the tachometer. The target must be at least the same size as the plastic cap diameter. Magnetic Sensor with amplifier: Pass a ferrous piece of metal in front of the permanent magnet built into the magnetic sensor or touch the magnetic sensor with a piece of metal and the on target indicator must appear on the tachometer. | Q. Can I use any type of Reflective tape?
A. No. Monarch’s tachometers and optical sensors must be used with part number T-5 reflective tape. The reflective tape is rated to 175°F or higher temperature tape may be purchased up to 500°F. The T-5WP is a 5-foot roll of waterproof tape. | Q. How do I calibrate my Self Powered Sensor?
A. To verify correct operation of the SPS-5 or SPLS-5, aim the ROS-5P, IRS-5P or RLS-5P sensor at a fluorescent light and observe 7,200 ± 2 RPM for 60 Hz and 6,000 ± 2 for 50 Hz operation. There is no calibration required for an SPS because there is no display on the interface module housing. They just produce TTL pulses. The accuracy is based on the data acquisition system receiving the pulses. | Q. What is the maximum length cable for my Sensor ?
A. Customers can increase the length of the cable on all Monarch sensors up to 500 feet and not have a problem with performance. |
| | Strobes | Q. How can I reset my PALM STROBE?
A. To reset your PALM STROBE to the factory settings, Hold the MODE button while pressing the power ON. |
| | OnTime Software | Q. How do I reset my password in OnTime Software?
A. PROCEED WITH CAUTION. Close all OnTime Applications. At the Windows Desktop go to "Start", "Run"
Type regedit and hit enter. Select HKEY_CURRENT_USER. Select "Software", "OnTimeW" Double click the folder. Go to the bottom of the list, double click on "SetupPass" and remove the current value. Accept the change. You can now set a new password from within the OnTime software. | Q. What is Condition Monitoring?
