General Information 1. General Information 1.1. Overview 1.1.1. 400 Series Family The Hastings 400 Series is a family of flow instruments which is specifically designed to meet the needs of the industrial gas flow market. The “I” family in the 400 Series features an IP-65 enclosure which allows the use of the instrument in a wide variety of environments. The 400 I products consist of four configurations: a flow meter, HFM-I-401, which has a nominal nitrogen full scale between 10 SLM

1.1.4. Additional Functions These instruments contain a number of functions in addition to reporting flow which include: • Settable alarms and warnings with semiconductor switch outputs • A digitally reported status of alarms and warnings such as overflow/underflow • A flow totalizer to track the amount of gas added to a system • A digitizing channel for an auxiliary analog signal • An internal curve fitting routine for “fine tuning” the base calibration • An alternate calibration

Installation 2. Installation Many of the functions described in this section require removing the enclosure front plate. Care must be taken when reinstalling this plate to ensure that the sealing gasket is properly positioned and the fasteners are secure to maintain CAUTION an IP65 compliant seal. 2.1.

2.4. Mounting the Electronics Remotely In order to maintain the integrity of the Electrostatic Discharge immunity both parts of the remote mounted version of the HFM-I-400 instrument must be screwed to a well grounded structure. The ferrite that is shipped with the instrument must CAUTION be installed on the cable next to the electronics enclosure. The electronics enclosure can be separated and relocated up to 30 feet away from the flow meter base. This requires a cable which is

In order to maintain the environmental integrity of the enclosure the power/signal cable jacket must have a diameter of .157 - .315” (4 – 11 mm). The nut on the cable gland must be tightened down sufficiently to secure the cable. This cable CAUTION must be rated for at least 85°C. 2.5.1. Power Supply Ensure that the power source meets the requirements detailed in the specifications section. Hastings offers several power supply and readout products that meet these standards and are

2.5.2.2. Voltage output If the flow meter is configured for a voltage output, the signal will be available as a positive potential on pin 4 relative to pin 3 of the terminal strip. Since these pins are galvanically isolated, the signal cannot be read by an indicator between pin 4 and pin 1 of the terminal strip. Pin 3 must be used as the return to properly read the output on pin 4. If an output that is referenced to power supply common is desired then pins 3 and 1 must be connected. It is

electronics enclosure. Only the state of jumpers 1, 2, and 5 affect the RS-232 operation. These jumpers are installed vertically over two pins when enabled and are numbered from left to right. Jumper 1 must be disabled for RS-232; jumper 2 is used to select half or full duplex; and jumper 5 is enabled when a hardware override of the baud rate (forcing it to 9600) is desired. These functions are summarized in Figure 2-6. 2.7.2. RS-485 If RS485 is specified on the order, the flow meter i

2.8. Alarm Output Connection The Hastings 400 Series flow meters include two software settable hardware alarms. Each is an open-collector transistor functioning as a semiconductor switch designed to conduct DC Alarm 1 current when activated. (See Figure 2-9.) These sink sufficient current to illuminate an external LED or to activate a remote relay and can tolerate up to 70Vdc across the transistor. The alarm lines and the alarm common are Alarm 2 galvanically isolated from all other

2.9. Auxiliary Input Connection The Hastings 400 Series flow meters provide an auxiliary analog input function. The flow meter can read the analog value present between pins 5 and 6 on the terminal strip (as shown in Figure 2-2) and make its value available via the digital interface. The accepted electrical input signal is the same as that configured for the analog output signal (4 – 20 mA, 0 -20 mA, 0-5 Vdc, 1-5 Vdc, or 0-10 Vdc). Unlike the analog output signal, which is isolated and

Operation 3. Operation The Hastings 400 Series flow meters are designed for operation with clean dry gas and in specified environmental conditions (See Section 1.2). The properly installed meter measures and reports the mass flow as an analog signal and, depending on the configuration and set up, as a digital response. Other features can assist in the measurement operation and provide additional functions. The following sections serves as a guide for correctly interpreting the analog and d
